INFRARED VIEWER SM-3R

The SM-3R is a high performance miniature infrared viewer fit comfortably in the palm of hand and is ideal for applications involving the alignment of infrared beams or optical fibers in a near-IR system.
Users may also mount the viewers on a post via the 1/4-20 internal threads, or they may use them as
hand-held devices. SM-3R infrared viewers are available in two versions: one with a spectral sensitivity that extends from 350 to 2000 nm and one with a 350 to 1700 nm spectral sensitivity.
