Info from website:

The FX8B is designed exclusively for operator convenience and performance. The FX8B features two projectors for a full-screen, side-by-side display of two images—without image overlap. Latent fingerprints may be compared with recorded prints; suspected counterfeit money may be compared with legal tender; and questioned documents and signatures may be compared with genuine articles. Two quartz halogen projection lamps are controlled by individual front-panel switches for dual or single unit usage. Optics carried by the turret automatically provide appropriate surface illumination. Each lamp compartment is monitored by a thermal switch which allows the silent-run fan to continue to operate even after shut off. A matched pair of color-corrected, side-by-side f/3.5 objective lenses provide 6.5X and 10X magnification. Control knobs raise and lower the unit’s two stainless steel surface platforms for image focusing.
