A High Resolution Shortwave Infrared Passive Athermalization System with Wide Temperature Range
A design of athermalized shortwave infrared optical system with wide field of view is introduced. The working wavelength is 0.9~1.7 μm, the resolution is 640 pixel×512 pixel, and total optical length is 55mm. The results show that the modulation transfer function (MTF) is above 0.6 at the spatial frequency of 20 lp/mm in the temperature range of -40 ℃~60 ℃. The system has the advantages of high image quality, wide temperature range, compact structure and low mass.
