Germanium optics for thermal cores
Knight Optical supplies Germanium (Ge) Optics for Infra-red systems over the waveband of 1.7 to 14µm. We offer Ge optics for MWIR (3 to 5µm) and LWIR (8 to 12µm) Imaging Systems.
Ge has a good transmission in the MWIR band, and can be used with Silicon or Zinc Selenide, given its refractive index range is higher than the two of them, to form corrected doublets and lens systems. These systems include, for example, Forward Looking Infra-Red (FLIR) systems, and thermography.
