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.
