4mm Dia. Laser Mirror Substrate

Product Details λ/10 and λ/20 Surface Flatness and 10-5 Surface Quality High Quality Fused Silica Substrates Imperial Sizes with Circular or Rectangular Geometries Window Substrates Also Available TECHSPEC Laser Mirror Substrates are manufactured from high quality fused silica and are designed for use with high power laser sources. These mirrors feature excellent surface specifications, including λ/10 and λ/20 surface flatness and 10-5 surface quality, to limit the possibility of reduced performance due to surface defects. The high surface quality of these mirror blanks also makes them ideal for use in demanding intra-cavity laser applications. TECHSPEC Laser Mirror Substrates are available in standard imperial sizes, with either circular or rectangular geometries. Please contact us if your application requires a custom size laser mirror substrate.
