Description

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.
