FJW - 80451 Find-R-Scope Continuously Variable Iris Attachment

The FJW 80451 Continuously Variable Iris Attachment is a valuable accessory designed to enhance the functionality of Find-R-Scope infrared (IR) viewers. This variable iris allows for precise control of intensity and increases the depth-of-field, reducing the need for constant refocusing when changing distances. It's specifically engineered for use with Find-R-Scope models that feature the Infragon objective lens, such as the 84499A, 84499A-5, 85268A, 85268A-5, 85100, 85100-5, 85100A, 85100A-5, 85050A, 85050A-5, 85051A and 85051A-5. The 80451 Continuously Variable Iris Attachment is also compatible with models 84499, 84499-5, 85100 and 85100-5 when paired with the standard Infragon lens. Note: this attachment is not necessary for C-mount lenses, as they already feature a built-in adjustable iris.
