Diffuser Lens Cap
When installed over the IR Illuminator, the Diffuser Lens Cap
spreads the laser energy over an angle of at least 45
degrees, allowing for illumination of a wider area. It is most
effective when used in conjunction with the Illuminator Focus
Ring adjusted to the widest beam (flood) setting. To use the
Diffuser Lens Cap, stretch it out and over the front of the IR
Illuminator so that it is snug and firmly in place. See Figures
2-15 and 2-16.
