flange mounted iris diaphragm for light sources model 71400

Overview

Manually operated iris diaphragms are an inexpensive and excellent option for light attenuation and can act as lens aperture stops as well. They are easily operated by the manual lever at the top of the diaphragm. These irises provide adjustable apertures, as small as 1 mm or as large as 36 mm, and have a standard 1.5 Inch Series flange for simple integration into Oriel^® lamp housings or detectors. If rod mounting is preferred, a 1/4-20 tapped hole is located on the bottom.

Useful for light attenuation or as light aperture stops
1.5 inch male and female flanges for simple coupling to Oriel components
Suitable for light sources up to 50 W
1/4-20 threaded hole for rod mounting
