IR Thermal Imaging Lenses

II-VI’s IR thermal imaging lenses are transmissive optics that are ideal for IR applications.

Available materials include:

  • Germanium (Ge)
  • Zinc selenide (ZnSe)
  • Zinc sulfide (ZnS)
  • Zinc sulfide multispectral (ZnS MS)
  • Silicon (Si)
  • Calcium fluoride (CaF2)
  • Amorphous material transmitting infrared radiation (AMTIR)

Geometries include:

  • Spheres
  • Aspheres
  • Diffractive
  • Freeform lens arrays

Optical coatings include:

  • High-efficiency BBAR (broadband antireflective)
  • High-durability, medium-efficiency BBAR
  • Diamond-like coatings (DLC)
  • Filters

Note: Most coating designs can be supplied thorium-free.
