Laser components require highly polished substrates as well as high performance coatings. Scattering of laser light, or worse, laser damage can occur if the substrate is made of inferior material or if it is inadequately polished. Although our coatings may be applied to a wide variety of substrates, we offer a popular selection of laser grade optical substrates.
Ultra-Violet grade synthetic fused silica provides the best Ultra-Violet and visible transmission characteristics and is a highly durable material. It is recommended for short wavelength applications. Laser grade BK7 optical glass is the most commonly used material for laser mirrors and windows. For applications where low thermal expansion is important we offer a range of pyrex and Zerodur™ substrates also.
