Product Description

The 80451 Variable Iris attachment works as an accessory to the standard lens. The variable iris is used to control intensity and to increase the depth-of-field. This reduces the necessity to refocus for changes in distance.

This variable irisis for use with FIND-R-SCOPE^®models that use the Infragon objective lens. The Infragon lens is standard with models 84499A, 84499A-5, 85268A, 85268A-5, 85100, 85100-5, 85100A, 85100A-5, 85050A, 85050A-5, 85051A and 85051A-5. This variable iris is also compatible with models 84499, 84499-5, 85100 and 85100-5 when used with the standard Infragon lens.

This item is not required for c-mount lenses. The c-mount lenses have an adjustable iris built-in.
