Product Description

The FIND-R-SCOPE^® 85763 50 mm, f/1.8 lens is for use with the following Infrared Camera part numbers; 85700, 85720, 85706 and 85726. It is an f/1.8 speed lens with built in iris. On these models it will provide a more narrow field of view and a larger display of target than the standard 25 mm f/1.4 lens. (Approximately a 14.6 x 11 degree field of view.)

This lens can also be used with all model Find-R-Scopes that use c-mount lenses.

The built-in manual iris can be used to control intensity and increase the depth-of-field. This helps to reduce the necessity to refocus for changes in distance.
