Flat Windows

Thorlabs offers flat windows fabricated from N-BK7, UV Fused Silica, Sapphire, Calcium Fluoride, Magnesium Fluoride, Potassium Bromide, Infrasil, Zinc Selenide, Silicon, Germanium, or Barium Fluoride. Our laser windows have a wavelength-specific AR coating centered around commonly used laser wavelengths and an optional wedge, while our precision windows are offered with or without a broadband AR coating.
