Product Family Description

  • UV, Visible, and NIR Anti-Reflection Coated Versions Available
  • High Tolerance for Precision Applications
  • Sizes Ranging from 5 - 50mm Diameters

Our precision TECHSPEC® λ/10 UV Fused Silica Windows feature laser-grade surface quality and parallelism. In addition, these windows will limit the transmitted wavefront distortion to λ/10. Available uncoated, or with anti-reflection coatings optimized for the UV or visible spectrum, the superior transmission characteristics and excellent thermal properties combined with high tolerance manufacturing specifications make these windows an excellent choice for more demanding applications.
