Graflex has developed a number of products meant to support our motorized zoom lenses and any other optical surveillance, targeting, or tracking system. The DIS-III is a PCB packaged system which transforms most any motorized zoom lens into a digitally controlled device. The ZHS-II heater system, developed as a zoom lens heater, includes a user or factory calibrated thermostat PCB and one, two, or three heater PCB’s to be mounted as desired to overcome low temperatures concerns. Our carbon fiber environmental enclosures provide a protective environment for large aperture surveillance sensors. Finally, our Boresight Compensation Devices are used to improve the boresight retention of our zoom lenses.
