Broadband Lens Design for SWIR/MWIR Applications

摘要

Infrared lenses, simultaneously colour corrected at multiple wavelengths from 10 to 5.0 µm, can be designed using several different technologies such as colour corrected lens triplets and three mirror anastigmats (TMA) telescopes. In this paper, several different broadband reflective and refractive lens design solutions are presented and compared. In addition, the problem of designing and producing broadband AR coatings for such a wide wavelength region will be considered. AT assessment of the advantages and disadvantages for each of the lens design forms will be provided together with a discussion of producibility limitations.
