Windows & Substrates

Windows & Substrates

Windows at their simplest are glass substrates with two highly parallel polished faces. Windows are used in a wide variety of applications and optical components and their main purposes are for transmitting light and for protection. Our catalog windows can be circular, square or rectangular in shape and come standard with various options for surface flatness, parallelism, wedge, and coating. Windows can also be used as the substrate for dielectric mirrors, beamsplitters, and dichroic filters and can also be used in interferometry as a reference flat or a compensator plate. Please contact our sales team with your requirements for a customized window if none of our many off-the-shelf options are suitable for your application.
