The best forensic optical comparator is available to you. Constructed of aluminum and steel, our forensic optical comparator was designed for maximum performance and convenience. A large 6" x 15" dual projection screen makes latent prints, money, documents, signatures and other types of evidence easy to see. You definitely won't have to strain your eyes to see these objects. Dual 300-watt quartz projection lamps light up the images, which can be placed side by side without overlapping each other. The lamps are controlled by individual front-panel switches so you can use one or both of them. Lamps have high- and low-power settings and are monitored by an internal switch which activates the 4" silent-running fan. A pair of objective lenses allow you to magnify images up to 10 times their original size. Focus controls are easy to reach and an adjustable sliding hood visor keeps the glare off your screen. There's plenty of room on the focusing platform to fit a variety of objects including money and even an 8" x 8" fingerprint record card which means you don't have to fold or bend them anymore to make them fit.
