Based on the investigation on the thermal properties of the diffractive lens
the paper introduces a method and some examples for designing the athermal diffractive/refractive optical system in the infrared region. An optical system at 3.2~4.5μm with 100% cold shield efficiency
5-degree field of view was designed
associated with high optical quality at the temperature ranging from -40℃ to 80℃. With this designing scheme
there is decrease in the number of optical components for a conventional optical system by one piece
and the weight can be reduced by 1/4
and expensive Se-Zn IR material is saved. Furthermore
the image quality approaching the diffraction limit in a larger spatial field view and wider thermal range can be obtained.
