红外折射-衍射混合光学系统的热差分析
Athermalization Analysis of Infrared Hybrid Refractive-Diffractive Optical Systems
摘要
分析了衍射光学元件在红外折射-衍射混合光学系统中的消热差特性, 指出衍射光学元件本身对热差的贡献是微小的, 但它的特殊色散特性却在红外折射-衍射混合光学系统设计中间接地起到了消热差的作用。 设计了适用于3～5 μm波段的红外折射-衍射混合光学系统并进行了分析。
Abstract
The athermalism of diffractive optical elements in infrared hybrid refractive-diffractive optical systems is analysed. It is shown that diffractive optical elements contribute a little to the thermal effects but their achromatic characteristic plays an important role in athermalization of infrared hybrid refractive-diffractive optical systems. An infrared hybrid refractive-diffractive optical system for 3～5 μm band with short total track is designed and discussed.
