This high performance infrared viewing unit is designed for viewing radiation in the 700-1300nm spectral region. By properly focusing the macro objective lens, objects from 3" to infinity can be brought into sharp focus. At the heart of the viewer is a high-resolution image converter, which converts near infrared radiation to a bright green light (550nm), that is easily seen through the eyepiece. A 1/4-20 tapped hole is located in the base of the handle for easy mounting to a tripod or laboratory bench. Common applications include observing the radiation emitted by IR sources (such as GaAs, IR LEDs, and Nd:YAG lasers), laser beam alignment/inspection, and photographic dark room use.
