The FIND-R-SCOPE^® CU100-27 Close Focusing Attachment Lens is for use with Infrared Viewers/Cameras part numbers 85400, 85345, 86400 and 86345. On these models this screw-on attachment will allow focusing closer to the target and provide a slightly wider field of view when at minimum focusing distance than the 85206, 16 mm f/1.6 lens alone. This Close Focusing Attachment Lens provides an increase in magnification of approximately 40% when used with the 16 mm lens.

This lens can also be used with model 89400 or with models 84499 and 84499-5 when the 85206, 16mm c-mount lens is used.

When used with models 84499 or 84499-5, and the 85206, 16 mm lens, combined they provide approximately a 57 degree field of view and a magnification increase of 40% at its close focus distance of 71mm, (2.8”). When used with model 89400, the lens provides approximately a 23 degree field of view and a magnification increase of 40% at its close focus distance of 71 mm, (2.8”).
