Abstract

To improve environmental adaptability, an optical system with passive optical athermalization was designed. This system adopts a transmission structure with a spectral range of 0.4-1.0μm, a focal length of 166mm, a F number of 3.7 and a field view of 5°. An optical system with passive optical athermalization should satisfy three constraints. The first is the power distribution of each lens. The second is the achromatic equation. The last one is the athermal equation. A reasonable optical material combination is obtained by solving the three conditional equations. Then the initial optical system is simulated and optimized by Zemax. In the end, this system gains good imaging quality in the working temperature range of 10-30°C.
