Product Description
The FIND-R-SCOPE® 85432 50 mm, f/1.3 lens is for use with Infrared Viewers/Cameras part numbers 85400, 85345,86400 and 86345. It is an f/1.3 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 16 mm f/1.6 lens.
This lens can also be used with model 89400 or with models 84499 and 84499-5 when the adapter ring is used.
When used with model 84499 or 84499-5, this optional f/1.3, 50 mm lens provides approximately a 16 degree field of view and a magnification of 0.05 at its close focus distance of 1m, (39.37”). When used with model 89400, the lens provides approximately a 7 degree field of view and a magnification of 0.05 at its close focus distance of 1m, (39.37”).
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.
