6.35mm Dia., 3.18mm Thick, Superpolished Laser Window Substrate

Product Details Superpolished on Both Surfaces with ≤1Å RMS Surface Roughness Low Scatter Surfaces Ideal for UV or High Power Laser Applications UV Fused Silica Substrates with Polished Bevels and Edges In-House Manufacturing Enables Custom Sizes and Shapes from 6 to 76.2mm and Surface Roughness <0.5Å TECHSPEC Superpolished Substrates are superpolished on both surfaces to achieve superior surface specifications, including ≤1Å RMS surface roughness. The superpolished surfaces of these windows reduce scatter, making them ideal for UV or high power laser applications where scatter is a concern. The low scatter of these windows also allows for their use as substrates for ion-beam sputtering (IBS) coatings. TECHSPEC Superpolished Substrates are used in metrology applications including cavity-ring down spectroscopy, scatterometry, and in ring laser gyroscopes, as well as in UV medical applications such as eye surgery. Please contact us if your application requires a Superpolished Substrate with a custom size, if you are interested in custom coating opportunities , or to discuss how these low scatter substrates will affect your coated optic performance. Single side superpolishing is also available.
