Lens Mounting

Lenses are not included with individual cameras.

The Back Flange Distance (BFD) is offset due to the presence of both a 1 mm infrared cutoff (IRC) filter and a 0.5 mm

sensor package window. These two pieces of glass fit between the lens and the sensor image plane. The IRC filter is

installed on color cameras. In monochrome cameras, it is a transparent piece of glass. The sensor package window is

installed by the sensor manufacturer. Both components cause refraction, which requires some offset in flange back

distance to correct.

For more information about the IRC filter, see

The camera has 6 MB flash memory for users to store data.

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.

Infrared Cut-Off

Warning! Cameras are sealed when they are shipped. To avoid

contamination, seals should not be broken until cameras are ready

for assembly on site.

Warning! Use caution when removing the protective glass or filter.

Damage to any component of the optical path voids the Hardware

Warranty. Removing the protective glass or filter alters the optical

path of the camera, and may result in problems obtaining proper

focus with your lens.
