Description:
IR Windows are Optical Windows designed for optimal performance in the Ultraviolet (UV) or 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.
GIAI 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.
Germanium (Ge) Windows are available off-the-shelf with two anti-reflection coating options: 3 - 12μm for mid-infrared or broadband multi-spectral applications, or 8 - 12μm for thermal imaging applications. Due to its high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended on these germanium windows for sufficient transmission in the region of interest. Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such, these germanium windows should be used at temperatures below 100°C. Germanium’s high density (5.33 g/cm3) should be considered when designing for weight-sensitive systems. The Knoop Hardness of germanium (780) is approximately twice that of magnesium fluoride, making it ideal for infrared applications requiring rugged optics.
