4. OVERVIEW

C11440-42U/C11440-42U01 is equipped with the new scientific image sensor “FL-400”, an advanced CMOS device that realizes the multiple benefits of high resolution, high readout speed, and low noise all at once. The camera provides 4.0 megapixels resolution at 30 frame/s (and up to 25 000 frame/s by sub-array readout) while achieving 0.9 electrons (median) 1.5 electrons (r.m.s) readout noise performance. Moreover, the camera delivers high sensitivity through its on-chip micro lens, 33 000:1 high dynamic range 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. The camera is the new scientific digital camera for life science microscopy, semiconductor inspection, x-ray scintillator readout or industrial imaging.

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 are greatly minimized. In addition, there is on-chip CDS (correlated double sampling) circuit, which plays an important role in achieving low noise. Moreover, the sensor features a split readout scheme in which the top and bottom halves of the sensor are readout independently, and the data of each horizontal line is read by 2 lines of column amplifier and A/D in the top and the bottom in parallel and simultaneously. As a result, it achieves very fast readout speed while keeping very good low-noise performance. The camera has lower readout noise (0.9 electrons (median), 1.5 electrons (r.m.s)) than the conventional cooled CCD camera. Moreover, high-speed readout (30 frame/s with 2048 pixels × 2048 pixels) with very low readout noise, which was impossible, can now be achieved.
(2) Cooling structure
In the camera, the FL-400 is cooled down by the peltier element to suppress the dark current. The camera has a special chamber structure to avoid the condensation.
(3) Pixel number and pixel size
The FL-400 sensor has 6.5 µm x 6.5 µm pixel sizes that is equivalent to conventional CCD image sensor (2/3 inch, 1.3 megapixels). Also, the camera can observe a wider field of view because the pixel number is about 3 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.
8
C11440-42U/C11440-42U01 Instruction manual_Ver.1.1
(5) Frame rate
The FL-400 realizes both low noise (0.9 electrons (median) 1.5 electrons (r.m.s)) and high speed readout (30 frame/s with 2048 pixels x 2048 pixels) simultaneously, by a split readout scheme in which the top and the bottom halves of the sensor are readout independently, and the data of each horizontal line is read by 2 lines of column amplifier and A/D in the top and the bottom in parallel and simultaneously.
(6) Real-time correction functions
When using the camera, there is a case that shading caused by uneven illumination or optics is not negligible in the image. Also, there are a few pixels in FL-400 that have slightly higher readout noise performance compared to surrounding pixels. For those cases, 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 sacrificing the readout speed at all.
(7) Interface
This camera has USB 3.0 interface. USB 3.0 interface is able to transfer 4 megapixels image with 30 frame/s. It is versatile interface. It transfers image with moderate transfer speed.
(8) Camera operation modes
The camera has three operation modes: 1) the free running mode, in which the exposure and readout timing are controlled by the internal microprocessor, and 2) the external trigger mode, in which the exposure and readout timing are decided by an external trigger. 3) the start trigger mode is used to start operating the camera by a trigger input for a continuous imaging.

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-400 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 between 20 ºC and 25 °C. Thus, the maximum temperatures to which the FL-400 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 temperature in order for cooling 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 and stopping current supply to Peltier element simultaneously. When the protection circuit is activated immediately turn off the power switch. Then investigate cause and remove the cause of the overheating and restart the camera.

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 5 minutes after cooling begins.
When the cables are connected, confirm the power switch of peripheral device is in the OFF position.

8-3 IMAGING

Start the control and imaging with the application software.
Note
Please refer to the instruction manual attached to the software for the way of using it and the details.

8-4 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. Entered light is converted to charge and converted to voltage in the pixel. The voltage of each pixel is output by switching the switch one by one. (Figure 9-1) The FL-4 double sampling) circuit, which plays an important role in achieving low noise. In addition, the FL-400 realizes both low noise and high speed readout simultaneously, by a split readout scheme in which the top and the bottom halves of the sensor are readout independently, and the data of each horizontal line is read by 2 lines of column amplifier and A/D in the top and the bottom in parallel and simultaneously.

C11440-42U/C11440-42U01 Instruction manual_Ver.1.1
The exposure and the readout method of FL-400 is 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 th
e object moves during the exposure, the affect of rolling shutter is very small.

C11440-42U/C11440-42U01 Instruction manual_Ver.1.1

9-2 READOUT METHOD (SCAN MODE)

The camera has the following scan modes.
(1) Normal readout
Perform charge readout from camera individually for all pixels.
(2) Binning readout
With this camera, 2×2 binning readout and 4×4 binning are available by adding the signal of adjacent pixels in the digital domain, Binning readout is a method for achieving high sensitivity in exchange for losing resolution.
(3) Sub-array readout
Sub-array readout is a procedure only a region of interest is scanned. It is possible to increase the frame rate by reducing the number of vertical lines scanned. When a target area is placed in the center of the screen, sub-array readout can perform the fastest readout. In sub-array readout, binning configuration is enabled.
Size and a position of the readout area can be configured according to the table below.
Settings
Binning Size Position Size Position
1×1 (Normal readout) 512 pixels 32 pixels 8 lines 4 lines
Horizontal Vertical
2×2 binning readout 256 pixels 16 pixels 4 lines 2 lines
4×4 binning readout 128 pixels 8 pixels 2 lines 1 lines
(4) Rapid Rolling Mode
This readout mode is preferred to be used when acquiring images of fast moving samples in order to minimize distortion come from rolling shutter.
Note
Please refer to 9-4 [FRAME RATE CALCULATION] about the frame rate of each readout
mode. However, Rapid Rolling mode is different from other modes.

C11440-42U/C11440-42U01 Instruction manual_Ver.1.1

9-3 CAMERA OPERATION MODES

The camera has the following operation modes.
(1) Free running mode
The camera has the free running mode which the exposure and readout timing can be set by software command and controlled by an 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.
(2) External trigger mode
The camera has various external trigger functions to synchronize the camera with the external equipment. In the external trigger mode, the external equipment becomes a master and the camera becomes a slave.
Edge trigger mode
The edge trigger mode is used so that the exposure starts according to an external signal.
Level trigger mode
The level trigger mode is used to control both exposure start timing and exposure time length by inputting external trigger pulses.
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.
(3) Start trigger mode
The start trigger mode is to start operating the camera by a trigger input for a continuous imaging.
Note
Please refer to 9-6 [TIMING CHART OF CAMERA OPERATION MODES] about the detail of
timing chart of these modes.

9-5 CONFIGURING EXPOSURE TIME

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 calculates a larger and closest value from the specified exposure time setting.
Exp1 = 3 ms to 10 s (at sub-array 129.99 µs to 10 s) Exp2 = Exp1 × 10
The actual exposure time setting for Rapid Rolling Mode is defined by the following formula.
The Exp1 values must be input to the calculation formula below in units of seconds.
32.4812 µs × Exp2
6
÷ 32.4812 µs (round up at decimal point)
10 µs × Exp2
Exp1 = 1 ms to 10 s (at sub-array 40 µs to 10 s) Exp2 = Exp1 × 10
6
÷ 10 µs (round up at decimal point)
Available setting range of the exposure time is the following.
Free running mode
Free running mode (at Sub-array)
External trigger mode
1 ms to 10 s (Rapid Rolling Mode)
129.99 µs* to 10 s
40 µs* to 10 s (Rapid Rolling Mode)
1 ms to 10 s (Rapid Rolling Mode)
Note
* 129.99 µs and 40 µs (Rapid Rolling Mode) for the Free running mode (at Sub-array) is
the minimum exposure time when sub-array is set to 8 lines vertically symmetric (4 lines in top half and 4 lines in bottom half) with respect to the horizontally center axis. The minimum exposure time vary depend on vertical line number of sub-array setting.

9-6 TIMING CHART OF CAMERA OPERATION MODES

9-6-1 FREE RUNNING MODE

The camera has the free running mode which the exposure and readout timing can be set by software command and controlled by an 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.
Note
9-6-1-1 Normal readout mode
The normal readout mode is suitable for observation, monitoring, field of view and focus adjustment, and animation because it can operate with full resolution, which is faster than the video rate (30 frame/s). 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.
Please contact to Hamamatsu subsidiary or local distributor for the detail of the timing information.

C11440-42U/C11440-42U01 Instruction manual_Ver.1.1
9-6-1-2 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 fastest frame rate is 30 Hz at full resolution even when the exposure time is short.

C11440-42U/C11440-42U01 Instruction manual_Ver.1.1

9-6-2 EXTERNAL TRIGGER MODE

The camera has various external trigger functions to synchronize the camera with the external equipment. In the external trigger mode, the external equipment becomes a master and the camera becomes a slave.
Not e
9-6-2-1 Edge trigger mode
The edge trigger mode is used so that the exposure starts according to an external signal. Exposure time is set by software command. In this mode, the exposure of the first line begins on the edge (rising/falling) timing of the input trigger signal into the camera. (1023H and 1024H in the following figure) The exposure of the second line is begun after the readout time of one line passes (1022H and 1025H in the following figure), and the exposure is begun one by one for each line.
Please contact to Hamamatsu subsidiary or local distributor for the detail of the timing information.
Figure 9-5 (Ex. rising edge)
25
C11440-42U/C11440-42U01 Instruction manual_Ver.1.1
9-6-2-2 Level trigger mode
The 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 exposure at the start of high or low period of the input trigger pulse and stops 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. The minimum trigger pulse width is 1 ms + 50 µs.

26
C11440-42U/C11440-42U01 Instruction manual_Ver.1.1
9-6-2-3 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 spinning disk's rotation speed, it is possible to eliminate uneven illumination (called banding noise) caused by variation of the spinning disk rotation speed. Also, it is useful for securing as long exposure time as possible while controlling the exposure start timings by external trigger signals.
(1) Normal operation (when the pulse count is set as 1.)
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 outside source and also when it is necessary to secure as long exposure time as possible. In the synchronous readout 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.
Figure 9-7 (Ex. rising edge)
27
C11440-42U/C11440-42U01 Instruction manual_Ver.1.1
(2) Pulse count
Also in the synchronous readout trigger mode, synchronous readout can be controlled by specifying, set by command, the number of timing pulses to determine the exposure time. The following figure shows the exposure timing when the pulse count is set as 3.
Figure 9-8 (Pulse count)
28
C11440-42U/C11440-42U01 Instruction manual_Ver.1.1
9-6-2-4 Start trigger mode
The start trigger mode is 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. For example, when it is necessary to measure the phenomenon after stimulation, it is possible to start continuous image acquisition at the stimulation timing.
The start trigger mode is 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).
Figure 9-9 (Ex. rising edge)
9-6-2-5 External trigger delay function
In most cases when a delay is needed between the laser pulse emission and the exposure start is needed, a delay unit is set between the laser and camera to control trigger timing. In each external trigger mode of the camera, the delay can be set to the trigger signal input to the camera by command. With this setting, a range of trigger can be arranged without a delay unit. The range for delay time is 0 µs to 10 s (10 µs steps).
29
C11440-42U/C11440-42U01 Instruction manual_Ver.1.1

9-6-3 TRIGGER 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 becomes the slave. There are three different trigger output functions as follows. Also, it can output continuous High output (High output fixed) or continuous Low output (Low output fixed).
These three different trigger output functions can be selected by software command, and they are output from Timing out connector.
Note
9-6-3-1 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.
Note
Please refer to Figure 9-3 to Figure 9-9 about details of each trigger output functions.
There is no output signal when the exposure time is less than the frame rate.

C11440-42U/C11440-42U01 Instruction manual_Ver.1.1
9-6-3-2 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 or pulse generator. It is possible to program and output a pulse that has an optional pulse width and an optional delay time to the end of readout timing or Vsync. The setting range for delay time is 0 µs to 10 s, and the setting range for pulse width is 10 µs to 10 s.
The relation between the parameter which can be set with each reference signal, and an output signal becomes below.
Reference signal Output signal

Vsync
Camera outputs a pulse after certain delay, from the end of sensor readout. Also the pulse width can be set.
Camera outputs a pulse after certain delay, from the beginning of readout. Also the pulse width can be set.
Figure 9-10
9-6-3-3 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 edge trigger mode, the next frame can start after the previous frame exposure is done. Thus, the camera cannot 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.

9-6-3-4 Multi-channel sync
The camera provides 3 programmable timing outputs from Timing out connector 1, 2 and 3 in a sequence. For example, these programmable timing outputs are useful to control a light source and get a color image.

9-7 REAL-TIME CORRECTION FUNCTIONS

There are a few pixels in FL-400 that have slightly higher readout noise performance compared to surrounding pixels. The camera has real-time variant pixel correction features to improve image quality. The correction is performed in real-time without sacrificing the readout speed at all. This function can be turned ON and OFF. (Default is ON)

10. PRECAUTION WHEN USING FL-400

This camera uses FL-400 (scientific CMOS image sensor). Careful attention must be paid to the following points when using FL-400:
(1) White spot
Subjecting FL-400 to extended exposures may cause failure in part of the silicon wafer, resulting in white spots. Currently this phenomenon is not currently preventable. If FL-400 is at a fixed temperature, recurrence of the white spot increases proportionally with the exposure time, so this can be rectified with dark subtraction*. Cosmic ray may generate white spot.
* After acquiring an image using a certain exposure time is loaded, the FL-400 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-400 because FL-400 may be damaged by over light.
