LASERSTEC use our super polished substrates and IBS coating to supply a series prisms. We can provides many kinds of high precision prisms, including Penta Prism, Beamsplitter Penta Prism, Right Angle Prism, and Corner Cubes which are manufactured using high purity fused silica substrates and dielectric coatings by IBS technology. These prisms have been specifically designed to withstand high-energy pulses and have a high damage threshold.
