Optical Quality Sapphire Windows

MSPW series plane parallel sapphire windows are designed for more demanding optical applications where image quality and birefringence effects are important. The raw material has negligible lattice distortion and is oriented with the optical axis normal to the faces to minimize the inherent birefringent properties of single crystal sapphire. Typical applications include:

  • Imaging optics
  • Polarization sensitive optics
  • Short wavelength (UV) optics
  • Focusing optics & reticles
  • Refractometer Windows
We maintain a substantial inventory of these parts and most are available for shipment from stock. For more demanding applications, we offer Laser Quality Windows.


Specifications:
Material:Optical Grade single crystal Sapphire
Orientation:C-axis perpendicular to the faces
Diameter Tolerance:+0.000" / -0.005"
