Muraviov O. Passive optical athermalization of infrared devices dioptric lenses

Basic factors which leads to dioptric IR lenses image quality change under an action of homogeneous temperature changes were determined. By the mathematical simulation and experimental analysis the temperature influence to aberration, spatially-frequency and power characteristics of dioptric IR lenses image quality was investigated. The problem is solved by development of passive optical athermalization method for dioptric IR three-component lenses, method of optimal combinations synthesis of athermal three-component IR lens materials, complex method for analysis of homogeneous temperature influence to IR lenses image quality characteristics.
