Laser Quality Sapphire Windows

MSLW Series plane parallel windows are designed for use in critical optical and laser applications where image quality and birefringence effects are important. The raw material has minimal lattice distortion and is oriented with the optic axis normal to the faces to minimize the inherent birefringent properties of single crystal sapphire. Flatness and surface finish are optimized to provide for the least amount of error in the transmitted wave front. Typical applications include:

  • Laser Mirrors
  • Laser Beam splitters
  • Laser Output Couplers
  • Imaging optics
  • Optical Flats & Etalons
We maintain a substantial inventory of these parts and most are available for shipment from stock.
