Sapphire optics for infra-red systems

Knight Optical can offer Sapphire (Al2 O3) Optics for Infra-red systems over the waveband of 0.2 to 5µm. We offer Al2 O3 optics for UV, Visible, NIR (0.9 to 1.5µm) and Mid-Waveband Infra-Red (MWIR, 3 to 5µm) Imaging Systems. Al2 O3  has hardness of about HK2000, which makes it a better choice for windows and outer elements of lens systems.

Al2 O3  has a 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
