Knight Optical’s Germanium Windows for Gas Detection
07 Jan 2020
Highly sought-after and known for their optimum IR transmitting abilities, our Germanium Windows are often specified for gas detection applications. Thanks to Germanium’s exceptional transmission at over 45% between 2-14µm and up to 45°C temperatures, our Windows are ideally suited to identifying gas wavelengths across the whole spectrum.
High in quality and precision, our extensive stock range of Germanium Windows are DLC/AR (Diamond-Like Carbon/Anti-Reflective) coated for 7-12µm and are available in a variety of lengths, thicknesses and tolerances for next-day dispatch. Alternatively, for devices requiring custom-tailored Germanium Windows, our team of Technical Sales Advisors can work alongside you to manufacture project-specific, customised Germanium Windows for a seamless fit. This service enables you to specify the exact requirements sought by your project, including size, thickness, tolerance, optical coatings and more.
Knight Optical also provides alternative optical components used in Gas Detection Systems; such as Interference Bandpass Filters, Front Surface Mirrors, Gas Cells and Singlet Lenses and Windows made from Germanium (Ge), Calcium Fluoride (CaF2), Silicon (Si), Quartz/Fused Silica, Magnesium Fluoride (MgF2) or Sapphire (Al2O3).
