Product Family Description

  • λ/4 Surface Flatness or TWD
  • Broadband Anti-Reflection Coating Options Available
  • Custom Coatings and Sizes Available for Volume OEM Quantities
  • Also Available with Laser Line V-Coats

TECHSPEC® λ/4 N-BK7 Precision Windows are ideally suited for industrial and low power laser applications. The high tolerance design yields minimal beam distortion and scatter. Broadband coating options extend the range of these precision windows through the visible and near-infrared spectra.

Note: New additions to this product family may be specified with a transmitted wavefront distortion (TWD) specification instead of a surface flatness. For more information on the difference between these two specifications, see our application note on Understanding Optical Windows
