Do not block ventilation openings
• To prevent overheating in the camera’s int erior, do not wrap the device in
cloth or other material, or in any way allow the camera’s ventil ation ports to
become blocked. If the camera is being operated in an enclosed
environment, ensure clearance of at least 10 cm from both the intake a nd
exhaust vents when setting up.
At its core, C11440-10C is equipped with the new scientific image sensor FL-280, an
advanced CMOS device that finally realizes the multiple benefits of high resolution, high
readout speed, and low noise all at once.
C11440-10C provides 2.8 megapixel resolution at 45 frames/s (and up to 1273 frames/s by
sub-array readout) while achieving 3 electrons r.m.s. readout noise performance. Moreover,
the camera delivers high sensitivity through its on-chip micro lens, 4500:1 high dynamic
range, on-chip analog gain and various correction features that make the camera suitable
for almost any scientific application from bright field imaging to low-light fluorescence
imaging across a wide spectral range. Various external trigger functions and timing output
functions ensure proper timing control with peripheral equipment to cover a wide range of
applications.
C11440-10C is the new scientific digital camera for life science microscopy, semiconductor
inspection, x-ray scintillator readout or industrial imaging.

C11440-10C Ver.1.2
5. FEATURES
(1) Readout noise
In the camera, the pixel amplifier is optimized: it has high gain from optimizing the
semiconductor process, and the difference among pixel amplifiers is greatly minimized .
In addition, there is the on-chip CDS (correlated double sampling) circuit, which plays
an important role in achieving low noise. Moreover, the data of one horizontal line is
read by the on-chip column amplifier and A/D in paral lel and simult aneously. As a result,
it achieves very fast readout speed while keeping very good low-noise performance.
The camera has lower readout noise (3 electrons r.m.s.) than the conventional cooled
CCD camera. Moreover, high-speed readout (45 frame/s with 1920 pixels × 1440
pixels) with very low readout noise, which was impossible, can now be achieved.
(2) Cooling structure
In the camera, the FL-280 is cooled down by the peltier element to suppress the dark
current. If FL-280 is exposed to the atmosphere, condensation of the moisture from the
air might occur. The camera has a special hermetic chamber structure to isolate the
sensor from the atmosphere, and the chamber is filled with nitrogen gas.
(3) Pixel number and pixel size
The FL-280 equipped in the camera has 3.63 µm x 3.63 µm pixel size that is about half
of the conventional CCD image sensor (2/3 inch, 1.3 megapixels). When using the
camera with a microscope, the number of photons coming to one pixel can be made
equal to the conventional CCD image sensor (2/3 inch, 1.3 megapixels) if 0.5x relay
lens is used. Also, the camera can observe a wider field of view because the pixel
number is about 2 times that of the conventional CCD image sensor (2/3 inch, 1.3
megapixels)
(4) Readout method
The camera has a variety of readout modes. In addition to full resolution readout mode,
sub-array readout and binning readout are supported.
(5) Frame rate (readout speed)
The FL-280 realizes both low noise (3 electrons r.m.s.) and high speed readout (45
frame/s with 1920 pixels x 1440 pixels) simultaneously, owing to 1 line parallel
simultaneous readout using column A/D.
(6) Real-time correction functions
When using the camera, there is a chance that shading caused by uneven illumination
and optics is not negligible in the image. Also, there are a few pixels in FL-280 that
have slightly higher readout noise performance compared with surrounding pixels.
Therefore, the camera has real-time offset level, shading and defective pixel correction
features to further improve image quality. The correction is performed in real-time
without scarifying the readout speed at all.
(7) CameraLink interface
The camera realizes 45 frames/s high-speed data transfer for 2.8 megapixels by using
the CameraLink interface. Data is output with 75 MHz x 2 tap (12 bits) that follows the
Base Configuration standard of CameraLink interface, and images can be transferred
into a personal computer by using a CameraLink interface board available in the
market.
8
(8) Camera operation modes
The camera has two operation modes: 1) the free running mode, in which the exp osure
and readout timing are controlled by the internal microprocessor, and 2) the external
control mode, in which the exposure and readout timing are decided by an external
trigger.

8. OPERATION
8-1 PRECAUTIONS
Be careful of the following when you operate the camera.
(1) Cooling method
Cooling of this equipment is done using a Peltier element. With a Peltier element,
when current is supplied, one surface is cooled, and the other surface is heated. The
FL-280 is positioned on the cooling side, and cooling is done by discharging the heat
from the heated surface. This cooling method is passive air-cooling.
(2) Ambient temperature
The recommended ambient temperature for camera operation is 20 °C. Thus, the
maximum temperatures to which the FL-280 can be cooled, and the stability of the
cooled temperature, are affected by the ambient temperature. The ambient
temperature should be maintained at a constant temp erature in order for cooli ng to be
effective.
(3) Protection circuit
A double protection circuit protects this camera’s thermoelectric cooling device. If the
heat dissipater becomes abnormally hot, the protection circuit sets off a buzzer alarm
from the camera while simultaneously cutting the current supply to the peltier element.
When the protection circuit operates like this, immediately turn off the power switch.
Then locate and remove the cause of the overheating and restart.
C11440-10C Ver.1.2
8-2 PREPARATION FOR IMAGING
Use the following procedure when starting operating of the camera.
(1) Connect devices as shown in Figure 7-1 before you start operation.
(2) Turn on the computer's power switch.
The cooling temperature becomes stable about 15 minutes after cooling begins.
• When the cables are connected, confirm the power switch of peripheral device is in the
OFF position.
8-3 END OF IMAGING
Carry out the procedure below when imaging is finished.
(1) End the imaging or transmission of image data with the application software.
(2) Turn off the power to the peripheral device.

9. DESCRIPTION OF VARIOUS FUNCTIONS
9-1 THEORY OF CMOS IMAGE SENSOR
The pixel of a CMOS image sensor is composed of the photodiode and the amplifier that
converts the charge into voltage. The entering light is converted into charge and converted
into voltage in the pixel. The voltage of each pixel is output by switching the switch one by
one. (Figure 9-1)
FL-280 that the scientific CMOS image sensor used in this camera has an on-chip CDS
(correlated double sampling) circuit, which plays an important role in achieving low noise. In
addition, FL-280 realizes both low noise and high speed readout simultaneously, owing to 1
line parallel simultaneous readout using column A/D.

C11440-10C Ver.1.2
The exposure and the readout method of FL-280 adopt the rolling shutter.
In the rolling shutter, the exposure and readout are done line by line. Therefore, the
exposure timing is different on one screen. (Figure 9-2) But even if the object moves during
the exposure, the affect of rolling shutter shows very little afterglow or smear in many cases.
Rolling shutter
Exposure length is same for all lines
Exposure timing is different for all lines
Figure 9-2 Readout timing of rolling shutter
9-2 READOUT METHOD (SCAN MODE)
(1) 1×1 Normal readout
Perform charge readout from cameraindividually for all pixels.
The frame rate of all pixel readout is 45 Hz.
(2) 2×2 binning readout
With this camera, 2x2 binning readout is available by adding the signal of adjacent
pixels in the digital domain, and is a method of achieving high sensitivity as a tradeoff
for resolution. The frame rate of all pixel readout is 45 Hz sa me as 1x 1 normal rea dout.
The digital output can be selected 14bit or 12bit when the 2x2 binning readout is
selected.
(3) Sub-array readout
Sub-array readout is a function to select an vertical area from among an effective
all pixel, and to read only the signal in the selection part from the FL-280. The
readout time of one frame can be shortened by using this function, and the frame
rate can be increased.
15
C11440-10C Ver.1.2
Typical examples of vertical area width and frame rate are shown in the following.
The Sub-array setting is specified by the vertical offset from 1
the selectable range is as follows.
The exposure time setting can be done by absolute value. The actual exposure time setting
is defined by the following formula, and the camera automatically calculate a larger and
closest value from the specified exposure time setting.
Vn × 14.81 µs + 20.94 µs
Available setting range of the exposure time is 20.94 µs to 10 s.
Vn: integer number (0 to 675)
16
C11440-10C Ver.1.2
9-4 FREE RUNNING MODE
The camera has the free running mode in which the exposure and readout timing can be set
by software command and controlled by the internal microprocessor. The free running mode
has normal readout mode (in which the exposure time is longer than the 1 frame readout
time) and electrical shutter mode (in which the exposure time is shorter than the 1 frame
readout time). These readout modes are automatically switched depending on the exposure
time setting.
9-4-1 NORMAL READOUT MODE
The normal readout mode is suitable for observation, monitoring, field of view and focus
adjustment, and animation because it can operate at 45 fps with full resolution, which is faster
than the video rate. In addition, the exposure time can be extended to collect more signals and
increase the signal-to-noise ratio if the object is dark. In the normal readout mode, the exposure
time is the same or longer than the 1 frame readout time. In this mode, the frame rate depends
on the exposure time, and it becomes frame rate = 1/exposure time. The maximum exposure
time is 10 s.
Figure 9-3
9-4-2 ELECTRICAL SHUTTER MODE
The electrical shutter mode is used to get a proper signal level when signal overflow
happens due to too much input photons in normal readout mode. In this mode, the frame
rate is 45 Hz at full resolution even when the exposure time is short.
Figure 9-4
17
C11440-10C Ver.1.2
9-5 EXTERNAL CONTROL MODE
The camera has various external control functions to synchronize the camera with the
external equipment. In the external control mode, the external equipment becomes a master
and the camera becomes a slave.
9-5-1 EDGE TRIGGER MODE
The edge trigger mode is used so that the exposure is synchronized with an external signal.
9-5-1-1 Normal edge trigger mode
The normal edge trigger mode is used so that the exposure starts according to an external signal.
Exposure time is set by software commend. In this mode, the exposure of the first line begins on
the edge (rising/falling) timing of the input trigger signal into the camera. (0H in Figure 9-5) The
exposure of the second line is begun after the rea dout time of one li ne p asses (1 H in Figure 9 -5),
and the exposure is begun one by one for each line. The example timing chart below shows a
rising edge trigger.
Figure 9-5
9-5-1-2 Global exposure edge trigger mode
The global exposure edge trigger mode is used when imaging with a pulsed light source such as
pulsed laser or flash lamp. The exposure time can be set by software command. In this mode,
the camera combines the frames right before and after the global exposure trigger signal
(falling/rising edge) into one frame and output them as one frame of data. The exposure time of
this second frame can be set by software command. Minimum value of exposure time setting is
about 22 ms (1 frame readout time).
18
9-5-2 LEVEL TRIGGER MODE
C11440-10C Ver.1.2
Figure 9-6
The level trigger mode is used to control both exposure start timing and exposure time
length by inputting external trigger pulses.
9-5-2-1 Normal level trigger mode
The normal level trigger mode is used to control both exposure start timing and exposure time
length by inputting external trigger pulses. In the mode, the camera starts the exposure at the
start of high or low period of the input trigger pulse and stops the exposure at the end of high or
low period of the input trigger pulse. The example below is for the trigger level High. The
exposure of the first line begins when the trigger signal becomes High, and the exposure of the
second line begins after the readout time of line one passes. Each exposure begins one by one
for each line. The exposure of the first line is finished when the trigger signal becomes low, and
signal readout is begun. The exposure time of each line is defined by the time that the input
trigger is high.
Figure 9-7
19
C11440-10C Ver.1.2
9-5-2-2 Global exposure level trigger mode
The global exposure level trigger mode is used to take a snapshot of a moving object with a
pulsed light source or get a momentarily illuminated event. The exposure time can be set by
software command. In this mode, the camera combines the frames right before and after the
global exposure trigger signal (falling/rising edge) into one frame and output them as one frame
of data. The exposure is finished when the trigger signal becomes inactive (falling/rising edge).
Minimum value of exposure time setting is about 22 ms (1 frame readout time).
Figure 9-8
9-5-3 SYNCHRONOUS READOUT TRIGGER MODE
The synchronous readout trigger mode is used for continuous imaging when it is necessary to
control the exposure start timing of each frame from an external source. It is useful for confocal
microscopy. For example, when the camera is used with a spinning disk confocal microscope
and the camera exposure time is synchronized to the spinnin g disk's rotation sp eed, it is possibl e
to eliminate uneven illumination (called banding noise) caused by variation of the spinning disk
rotation speed. Also, it is useful for securing as long an exposure time as possible while
controlling the exposure start timings by external trigger signals.
9-5-3-1 Normal synchronous readout trigger mode
The normal synchronous readout trigger mode is used for continuous imaging when it is
necessary to control the exposure start timing of each frame from an outside source and also
when it is necessary to secure as long an exposure time as possible. In the synchronous read out
trigger mode, the camera ends each exposure, starts the readout and also, at the same time,
starts the next exposure at the edge of the input trigger signal (rising /falling edge). That is, the
interval between the same edges of the input trigger becomes the exposure time.

C11440-10C Ver.1.2
Figure 9-9 (rising edge)
9-5-3-2 Normal synchronous readout trigger mode (Pulse count)
Also in the normal synchronous readout trigger mode, syn chronous rea dout can be controlled by
specifying, set by command, the number of timing pulses to use to determine the exposure time.
Figure 9-10 shows the exposure timing when the pulse count is set as 3.
Figure 9-10 (Pulse count)
21
C11440-10C Ver.1.2
9-5-3-3 Current synchronous readout trigger mode
In the current synchronous readout trigger mode it is possible to co ntrol the expo sure start timi ng
by using ACT command from application software. First, the camera is set to be idle condition by
ACT S command input. In idle condition, the camera does not start exposure even by a trigger
signal in yet. Then, the camera start an exposure by ACT I command and then start to readou t by
input external trigger.
(In the normal synchronous readout trigger mode, the camera does not readout by the first
trigger pulse after ACT I command.)
Figure 9-11
9-5-4 START TRIGGER MODE
The start trigger mode is used to start operating the camera by a trigger input for a
continuous imaging. It is useful to secure the frame rate as fast as possible when continuous
image acquisition and not to sacrifice the exposure time. Example, when it is necessary to
measure the phenomenon after stimulation, it is possible to start continuous image
acquisition at the stimulation timing.
9-5-4-1 Normal start trigger mode
The start trigger mode is used to start operating the camera by a trigger input for continuous
imaging, and it works at the highest frame rate because it is operated in internal trigger
mode. In the start trigger mode, the camera starts exposure and switches to internal trigger
mode by the edge of an external trigger signal (rising / falling edge).
22
C11440-10C Ver.1.2
Figure 9-12 (rising edge)
9-5-4-2 Current start trigger mode
In the current start trigger mode it is possible to control the exposure start timing by using a
command from application software and external trigger pulses. The fastest frame rate is
possible because the camera works in the internal trigger mode. It is possible to control the
exposure start timing from application software by using ACT commands. First, the camera is set
to be idle condition by ACT S command input. In idle condition, the camera does not start
exposure even by a trigger signal in yet. Then, the camera starts an exposure by ACT I
command, and then the camera starts 2nd frame exp osure by input external trigger an d switches
to internal trigger mode.
(In the normal start trigger mode, the camera does not read out by the first trigger pulse af ter ACT
I command.)
Minimum value of exposure time setting is about 22 ms (1 frame readout time).
Figure 9-13
23
C11440-10C Ver.1.2
9-5-5 EXTERNAL TRIGGER DELAY FUNCTION
In most case when a delay between the laser pulse emission a nd the exposure st art is ne eded, a
delay unit is set between the laser and camera to control trigger timing. In each external trigger
mode of the camera, the delay time can be set to the trigger signal input to the camera by
commands. Therefore, a range of trigger can be arranged without a delay unit.
9-6 TRRIGER OUTPUT
The camera provides a range of trigger output signals to synchronize with an external
instrument, and the camera becomes the master and the external instrument the slave.
There are three different trigger output functions as follows. Please refer to Figure 9-3 to
Figure 9-13.
- Global exposure timing output
- Programmable timing output
- Trigger ready output
These three different trigger output functions can be selected by software command, and they
are output from PIN5 of timing I/O connector (Refer to Figure 13-2)
9-6-1 GLOBAL EXPOSURE TIMING OUTPUT
It shows the global exposure timing where all lines expose at the same time. There is a case
that one event is divided into two frames because the timing of the exposure in each line is
different for the rolling shutter. However, by using the Global exposure timing output the
global exposure becomes possible for the phenomenon that happens for this period. Global
exposure timing output shows the period where all lines expose at the same time.
9-6-2 PROGRAMMABLE TIMING OUTPUT
By using the programmable timing output, synchronizing external devices is simple. A system
that needs simple timing signal does not require a delay unit nor pulse generator. It is possible to
program and output a pulse that has an optional pulse width and an optional delay time to the
exposure start timing of the camera by command.
The setting range for delay time is 0 µs to 10 s, and the setting range for pulse width is 20 µs to
10 s.
9-6-3 TRIGGER READY OUTPUT
The trigger ready output is useful to make the frame intervals as short as possible in external
trigger mode. For example, when the camera is working in the edg e trigger mo de, the next frame
can start after the previous frame exposure is done. Thus, the camera can't accept a trigger for
the next frame during the exposure period. To reduce useless time to be as short as possible, it
is necessary to know the period when the camera can accept a trigger for the next frame. The
trigger ready output shows the trigger ready period when the camera can accept an external
trigger in the external trigger mode.
24
C11440-10C Ver.1.2
9-7 ANALOG GAIN FUNCTION
The camera features an on-chip gain control capability that can multiply the analog signal in
sensor prior to converting it into a digital signal. This has the effect of reducing the
quantization error in the A/D converter, and the readout noise can be lowered to 3 electrons
(r.m.s) at analog gain 8x.
When low-light sample imaging in a short time is necessary and the output signal level is only a
few to a few dozen ADU out of 12 bits (4096 ADU), the image quality can be improved by
increasing the analog gain. It is necessary to note that the conversion coefficient* of the camera
changes when the analog gain is increased.
The setting range for the relative value register is 0 to 255. Parameter 0 is correspond to 1x,
255 is correspond to 8x.
9-8 REAL-TIME CORRECTION FUNCTIONS
There is a chance that Shading caused by illumination and optics can't be negligible in the
imaging with camera. The camera has the real-time offset level, shading and defective pixel
correction features for a further image quality improvement. The correction can be effective
in real-time without scarifying the readout speed at all.
25
C11440-10C Ver.1.2
10. PRECAUTION WHEN USING FL-280
This camera uses FL-280 (scientific CMOS image sensor). Careful attention must be paid to
the following points when using FL-280:
(1) White spot
Subjecting FL-280 to extended exposures may cause failure in p art of the sili con wafe r,
resulting in white spots. This phenomenon is not currently prevent able. If FL-280 is at a
fixed temperature, recurrence of the white spot increases proportionally with the
exposure time, so this can be rectified with dark subtraction*. Atomic ray may generate
white spot.
* After an image made using a certain exposure time is loaded, the FL-280 is exposed to darkness for the same
amount of time, and another image is obtained. After this, the difference between the images is determined, and the
data for the dark portion of the original image is nullified.
(2) Folding distortion
A rough-edged flicker may be visible when imaging striped patterns, lines, and similar
subject matter.
(3) Over light
CAUT ION
• Be careful not to input too strong light such as high-energy laser into
FL-280 because FL-280 may be damaged by over light.
11. MAINTENANCE
11-1 CARE
Clean the exterior with a soft, dry cloth.
• Do not use a wet cloth, dirty cloth.

13-2-2 CAMERALINK INTERFACE
Camera Link interface is a standard of digital interface for industrial digital cameras. It
transfers 28bit digital data (TX0 to TX27) by converting parallel data to only 5 signals (X0,
X1, X2, X3, XCLK) of serial data. This camera is compatible to CameraLink interface / Base
configuration 12 bit 2TAP digital camera standards at 1x1 normal readout mode, and 14 bit
digital camera standards at 2x2 binning readout mode.
(1) CameraLink connector pin assignments (SDR-26)
Camera connector Frame grabber connector Channel Link signal
This signal synchronizes in the image data from FL-280, and it is outputted.
Each digital data is effective with the period of “ON” of this signal.
zLVAL (Line Valid signal)
This signal show the period during which the line part of the image data from FL-280 is in effect.
This is “ON” when during the period the line is active.
zFVAL (Frame Valid signal)
This signal shows the period during which the vertical part of the image data from FL-280 is in effect. This
is “ON” during the period the frame is active.
zDB0 to DB13 (Digital image data)
This is the image signal data from FL-280 converted A/D. DB0 is the LSB(least significant bit),
DB13 is the MSB (most significant bit).
