Germanium Meniscus Lenses.

Alkor Technologies - manufacturer of Germanium meniscus lenses for Thermal Imaging Cameras and Pyrometry.

  • High Index of Refraction
  • Minimal Chromatic Abberation Due to Low Dispersion
  • Perfect for Rugged IR Application
  • Custom Meniscus Germanium lenses
  • Available with AR or DLC coating
  • Check also our plano-convex Germanium lenses

Germanium Meniscus Lenses are designed for for demanding infrared applications including infrared imaging or surveillance, remote sensing, or infrared spectroscopy. germanium Meniscus Lenses offer superior spherical correction and smaller spot size than comparable focal length Germanium planoconvex lens.
