Optics Block
The 4-channel (dual compensated) optics-block
is the heart of the Searchpoint OPTIMA PLUS.
It is specifically designed to compensate for
changes in the external environment similar to 2-
channel designs, but also compensates for long
term component drift such as infrared sources and
detectors. This combined with the de-focussed
beam provides the Searchpoint OPTIMA PLUS
with the most stable optics design possible.
