Beam Samplers are used to pick off the sample of a light beam by using the Fresnel reflection from uncoated surfaces. Beam samplers are used for monitoring applications where disturbance of the transmitted beam must be kept minimum. The back surface is wedged to avoid internal fringes and is anti-reflection coated to remove ghost images. Custom Sizes and anti-reflection coatings are available on special request.
