4.5 Dust Protection
The camera housing is designed to prevent dust from falling directly onto the sensor's protective glass surface. This is
achieved by placing a piece of clear glass (monochrome camera models) or an IR cut-off filter (color models) that sits
above the surface of the sensor'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 particles, the likelihood of interference
from the dust (assuming non-collimated light) and the possibility of damage to the sensor during cleaning is reduced.
n Cameras are sealed when they are shipped. To avoid contamination, seals should not
be broken until cameras are ready for assembly at customer's site.
n Use caution when removing the protective glass or filter. Damage to any component of
the optical path voids the Hardware Warranty.
n Removing the protective glass or filter alters the optical path of the camera, and may
result in problems obtaining proper focus with your lens.
