beam sampler / optical

If a user needa an Ultrafast Laser Beam Sampler which is designed to minimize pulse dispersion while also splitting off, then this product would be the right choice. BK 7 substrate is not coated on the front surface to ensure beam division by Fresnel reflection.

To prevent ghosting, the back surface is coated with anti-reflection and a slight wedge in the substrate virtually stops internal fringes. As for the polarization of the incident beam, its front surface reflection from 1-10% is achieved at a 45? incidence.
