Design of refractive optical lenses for an infrared camera

Abstract

Optical design for thermal IR camera is challenging: - the lack of glass materials limits the optimization. - achromatization and athermalization of the lens assembly requires a careful engineering. On the other hand, a refractive lens system offers a wider field of view with a better compactness than a reflective system. This Master thesis will survey the capability of a refractive design to accommodate the requirements of the OUFTI-NEXT payload. Optical performance such as imaging spatial resolution will be constrained with respect to mass and volume requirements.
