UV Broadband Beam Samplers
Newport's UV broadband beam samplers are optimized to split off, or sample, a beam by Fresnel reflection. This optic is ideal for typical beam monitoring applications where minimum disturbance of the transmitted beam is necessary.
Beam Sampler for Ultrashort Pulses
Our 3 mm thick Ultrafast Laser Beam Sampler is designed to minimize pulse dispersion while splitting off, or sampling, a beam by Fresnel Reflection for beam monitoring applications. The N-BK7 substrate is uncoated on the front surface to achieve beam division by Fresnel Reflection. The back surface is antireflection coated to prevent ghosting. A slight wedge in the substrate virtually eliminates internal fringes.
Broadband Beam Samplers
Broadband 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. The optic's back surface is slightly wedged and AR coated to prevent ghosting.
