The 10B20-01NC.2 Ultrafast Laser Beam Sampler is designed to minimize pulse dispersion while splitting off, or sampling, a beam for monitoring applications. This 1.0 inch (25.4 mm) diameter beam splitter is 3.0 mm thick. It is uncoated on the front surface to achieve beam division by Fresnel Reflection, and the back surface is antireflection coated to prevent ghosting. A slight wedge in the substrate virtually eliminates internal fringes.
