+55 11 2839-3209

Laser Line Anti-Reflection Coated Precision Windows

  • Made of high quality UV FS and BK7
  • AR coated at 266 nm, 355 nm, 532 nm or 1064 nm

Featuring high optical transmission with little distortion of the transmitted signal, precision windows are a good solution for Nd:YAG laser applications that require protective windows.
