Beam Samplers

Beam Samplers split off, or sample, 1-10% of a beam's energy via Fresnel reflection from a single uncoated surface. This enables beam monitoring with minimal transmitted power loss.  Beam Samplers are typically used for monitoring applications where optical losses and wavefront distortions of the transmitted beam should to be kept to a minimum. The optic's back surface is slightly wedged and AR coated to prevent ghosting.
