Introduction
Cleaning optics
Caution
AVT does not warranty against any physical damage to the sensor/filter/protection glass or lenses. Use utmost care when cleaning optical components.
Caution
Do not touch any optics with fingers. Oil from fingers can
damage fragile optical coatings.
Identifying debris
Debris on the image sensor or optical components appears as a darkened area
or smudge on a camera image. Do not confuse this with a pixel defect which
appears as a distinct point.
Locating debris
First determine whether the debris is on the sensor glass, IR filter (if used), or
lens. The farther away the debris is from the sensor, the blurrier the debris
appears on a camera image.
Stream a live image from the camera using a uniform target, such as a piece of
paper. To determine if the debris is on the camera lens, rotate the lens independent of the camera. If the spot moves, the debris is on the lens. Otherwise, the
debris is on the IR filter (if used) or sensor glass.
Color cameras with IR filter
Prosilica GE color cameras are equipped with an IR filter. With no lens or lens
cap on a camera, the IR filter is exposed and debris can accumulate on it. This is
the most probable location for debris. It should not be necessary to remove the
IR filter for cleaning. Clean the outside of the IR filter glass using the techniques explained in the next section.
If it is determined that the debris is on the inside surface of the filter glass, or
on the sensor glass, IR filter removal is necessary. Depending on the manufacturing date of your Prosilica GE camera, the IR filter may be slot type, or pinhole
type. Slot type filters can be removed using a small flat head screw driver. Pinhole type filters require a pin spanner wrench for removal.
Prosilica GE Technical Manual V2.0.3
9
Introduction
Note
A pin spanner wrench suitable for IR filter removal is available
for purchase from AVT.
AVT P/N: E9020001
Cleaning with air
Blow directly on the contaminated surface with moderate pressure, clean compressed air.
Caution
View a live image with the camera after blowing. If debris is still present, repeat
the process until it is determined that the particulate cannot be dislodged. If
this is the case, proceed to the contact cleaning technique.
Contact cleaning
Do not exceed 6 bar (90 psi). If using canned air, approximately ~ 4.8 bar (70 psi) when full, do not shake or tilt the
can, as extreme changes in temperature due to sudden cold
air can crack the optic glass.
Only use this method if the above air cleaning method does not sufficiently
clean the surface. Use 99% pure isopropyl alcohol and clean cotton swabs. Wet
the swab in the alcohol. Quickly wipe the optics in a single stroke. Prolonged
exposure of alcohol on the swab can cause the swab glue to loosen and transfer
to the optic glass. Do not reuse the same swab. Repeat this process until the
debris is removed. If this process fails to remove the debris, contact AVT.

Filters
All Prosilica GE color models are equipped with an infrared block filter (IR filter). This filter is employed to prevent infrared wavelength photons from passing to the sensor. In the absence of IR filter, images are dominated by red and
incapable of being properly color balanced. Monochrome cameras do not
employ an IR filter.
The figure below shows the filter transmission response for the IRC30 filter
employed in the Prosilica GE cameras.

I/O definition
Camera power
The Prosilica GE camera family supports a wide input power voltage range. The
camera will not power in reverse polarity. Exceeding the voltage range specified
below will damage the camera.
Caution
5–24 V. 12 V nominal.
Note
Isolated IO GND
Isolated IO GND must be connected to the user’s external circuit ground if In 1,
Out 1, Out 2, Out 3, RxD RS-232, and TxD RS-232 is to be used. Note that Isolated IO GND is common with power ground; however, it is good practice to provide a separate ground connection for power and signaling when designing the
cabling.
RxD RS-232 and TxD RS-232
These signals are RS-232 compatible. These signals allow communication from
the host system via the Ethernet port to a peripheral device connected to the
camera. Note that these signals are not isolated; therefore, cabling should be
carefully designed for the noisy environments.
A 12 V power adapter with barrel connector is available for purchase from AVT:
•P/N 02-8005C North America Supply.
•P/N 02-8010C Universal Supply.
Input triggers
In 1
In 1 allows the camera to be synchronized to an external event. The camera can
be programmed to trigger on the rising edge, falling edge, both edges, or level
of this signal. The camera can also be programmed to capture an image at some
programmable delay time after the trigger event.

Registered exposure time Exposure time value currently stored in the camera
memory
Exposure start delayRegistered exposure time subtracted from the read-
out time and indicates when the next exposure
cycle can begin such that the exposure will end

Trigger rules
Note
The user trigger pulse width should be at least three times the
width of the trigger latency as indicated in Chapter
Specifications on page 12.
•The end of exposure will always trigger the next readout.
•The end of exposure must always end after the current readout.
•The start of exposure must always correspond with the interline time if
readout is true.
•Exposure start delay equals the readout time minus the registered expo-
sure time.
Triggering during the idle state
For applications requiring the shortest possible Trigger Latency and the smallest
possible Trigger Jitter the User Trigger signal should be applied when Imaging is
false and Idle is true. In this case, Trigger Latency and Trigger Jitter are as indi-
cated in the camera specifications.
Triggering during the readout state
For applications requiring the fastest triggering cycle time whereby the camera
image sensor is exposing and reading out simultaneously, apply the User Trigger
signal as soon as a valid Trigger Ready is detected. In this case, Trigger Latency
and Trigger Jitter can be up to 1 row time since Exposure must always begin on
an Interline boundary.

Firmware update
Firmware update
Firmware updates are carried out via the GigE connection. AVT provides an
application for all Prosilica GE cameras that loads firmware to the camera using
a simple interface. New feature introductions and product improvements motivate new firmware releases. All users are encouraged to use the newest firmware available and complete the firmware update if necessary.

This section provides the performance information which identifies the impact
of reducing the region of interest on the camera’s maximum frame rate.
Note
Prosilica GE680
•Frame rate data was generated using StreamBytesPerSecond = 124 MB/s and an 8 bit pixel format such as
Mono8, BayerGR8, or BayerRG8. Frame rates may be
lower if using network hardware incapable of 124 MB/s.
•The camera frame rate can be increased by reducing the
camera's Height attribute, resulting in a decreased
region of interest (ROI) or “window”.
•The camera frame rate can also be increased by increasing the camera's BinningY attribute, resulting in a vertically scaled image (less overall height with same field of
view).
•There is no frame rate increase with reduced width.
