Prosilica GE Technical Manual V2.0.4

Introduction
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 manufac-
turing 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. Pin-
hole type filters require a pin spanner wrench for removal.
Cleaning with air
Blow directly on the contaminated surface with moderate pressure, clean com-
pressed air.
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
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.
Note
A pin spanner wrench suitable for IR filter removal is available
for purchase from AVT.

Caution
Do not exceed 6 bar (90 psi). If using canned air, approxi-
mately ~ 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.
