Knight Optical's Sapphire Windows for Infrared Systems | |
30 May 2017
Knight Optical offer a range of Stock Sapphire Windows, for use within Infrared Systems. Knight Optical can offer Sapphire (Al2O3) Optics for Infra-red systems over the waveband of 0.2 to 5µm. We offer Sapphire optics for UV, Visible, NIR (0.9 to 1.5µm) and Mid-Waveband Infra-Red (MWIR, 3 to 5µm) Imaging Systems. Sapphire has hardness of about HK2000, which makes it a better choice for windows and outer elements of lens systems. Sapphire has good transmission in the MWIR band, and can be used with optical glass in the NIR, and with Silicon or Germanium in the MWIR, to form well corrected doublets and lens systems. These systems include, for example, Forward Looking Infra-Red (FLIR) systems, and thermography. Al2 O3 has a refractive index of about 1.9288no 1.9174ne at 200nm through to 1.623no 1.615ne in the IR (5µm). This pairing will allow for the design and manufacture of a colour corrected lens that can be used in broad spectrum thermal imaging systems. We hold a large inventory of Random Cut and C-Cut Sapphire Windows.
Typical specs: All our Sapphire Windows are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our FIBSA, and Trioptic Prism Master. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components. Contact our technical sales team to discover how Knight Optical’s high quality Sapphire Windows and superior service can improve your instrumentation and supply chain experience.
