摘要

Ultraviolet (UV) spectrum of 200nm-300nm from the sun is absorbed by the ozone layer around the earth, which forms the solar-blind spectral region near the ground. Within this spectral region, UV signal interference will be very small. By the characteristics of solar-blind spectral region, it can be used in the fields such as prevention of forest fires, missile approach warning etc. An optical system with FOV 46° is designed for missile approach warning in this paper. To enhance the FOV enlarge the aperture and improve the image quality, two aspheric surfaces and one binary element are adopted in the optical system. PIXIS2048BUV-type camera is selected as the detector of the system, which has pixel size 13.5μm×13.5μm and imaging area 27.6mm × 27.6mm. After optimization, the RMS radius for maximum FOV is 18μm, which is slightly larger than one pixel size. For other FOV, the RMS radius are all much less than the pixel size. From the encircled energy curve, over 80% of the energy from the object is converged within the circle of radius 6.5μm. Point spread function of each FOV is high enough, which shows the designed optical system has good convergent degree of energy as an energy system.
