Dust Protection
Cameras are sealed when they are shipped. To avoid contamination,
seals should not be brok en until cameras are ready for assembly at
customer's site.
Do not remove the protective glass. Doing so can void the Hardware
Warranty described at the beginning of this reference manual.
The case is designed to prevent dust from falling directly onto the CCD's protective glass surface.
This is achieved by placing a piece of clear glass (monochrome camera models) or IR cut-off filter
(color models) that sits above the surface of the CCD's glass. A removable plastic retainer keeps
this glass/filter system in place. By increasing the distance between the imaging surface and the
location of the potential dust par ticles, the likelihood of interference from the dust (assuming non-
collimated light) and the possibility of damage to the sensor during cleaning is reduced.
