    UV and IR Windows

    UV Windows and IR Windows are Optical Windows designed for optimal performance in the Ultraviolet (UV) and Infrared (IR) spectrums. UV Windows are used in many laser applications. IR Windows are ideal for use in FTIR spectroscopy, in addition to thermal imaging, FLIR, or medical systems. Optical Windows do not introduce optical magnification into a system. Optical Windows should be chosen based on the substrate’s mechanical or optical properties.

    Edmund Optics offers a wide range of Optical Windows, including either Ultraviolet Windows or Infrared Windows in multiple anti-reflection coating or substrate options. Substrate options include materials such as UV Fused Silica, Calcium Fluoride (CaF2), Magnesium Fluoride (MgF2), Potassium Bromide (KBr), Sapphire, Silicon (Si), Sodium Chloride (NaCl), Zinc Selenside (ZnSe), or Zinc Sulfide. Metalized Windows are offered for soldering or bonding directly into an opto-mechanical assembly. IR Windows Kits contain some of Edmund Optics’ most popular Infrared (IR) Windows.
