Light Source Safety Shutter, Manually Operated, 1.5 Inch Series Flange

The 71430 Manual Shutter is a low cost and easy to use device for reliably checking radiometric zero. The easily accessible lever moves a slide in and out of the optical path. The slide is shaped as a crescent moon, so that as it closes down the output beam shape remains circular. It has the same aperturing effect as an iris would.

It has 1.5 Inch Series male and female flanges for easy coupling to Oriel products.
