Product Description Product Detail Specifications Drawings Catalog PDF
Product Description
Three aperture sizes of the 935 variable attenuators are available—3, 5, and 10 mm diameter. These attenuators are based on the principle of Fresnel reflection from four uncoated, counter-rotating UV fused silica wedged plates.
