Plano optics (or optical flats) can have one or both sides that are polished to specification, depending on the application. One-sided optical flats are often used as reference surfaces to test the flatness of optical windows, prisms, and other plano optics. Double sided optical flats can be test plates as well, but can also serve as optical windows due to their ability to transmit light. The material that optical windows are made from depends on the application, as different materials transmit light at different wavelengths.
Vertex Optics has the equipment and expertise to produce prototype to production quantities of plano optics such as prisms and optical windows. Vertex has decades of knowledge producing plano optics from a variety of different materials, depending on your application requirements. From soft crystals, all optical glasses and hard ceramics, we can deliver plano optics that meet your specifications.
