Abstract
Refractive optical systems having first and second lens systems are transmissive to infrared radiation. The first lens system includes one of BaFand CaF. An exemplary second lens system includes an optical material selected from at least spinel, MgF, and aluminum oxynitride. Such exemplary refractive optical systems provide correction of chromatic aberration in multiple wavelength bands.
