Paper Abstract

In this work, the design study of a switchable dual field of view thermal optical system for 3-5 μm is presented. A mechanical holder switches in and out lenses to the whole optical system to change the focal length from 60. A cooled 320×256 focal plane array with 30 μm pixel pitch is imaging the rays gathered by thermal optics. To avoid vignetting which is caused by the presence of the detector cold shield, a relay lens is used to image the entrance pupil of optics on the cold shield.
