Wide-temperature-range athermalization for MWIR hybrid refractive/diffractive optical system
摘要
Abstract
A hybrid refractive/diffractive Petzval lens has been designed. Its working wavelength range is 3. 2-4. 5 μm, full field of view is 8.42°. efficient focal length is 95 mm and back focal length is 60. 5 mm. The Petzval lens consists of four lenses, including two aspheric surfaces and a diffractive surface, which make the Petzval lens compact and light. Its modulation transfer function is above 0. 7 in the temperature range from —80 to 160 ℃. The Petzval lens is compatible with the uncooled staring focal plane array which has a format of 320X240 and the pixel pitch of 35 μm关键词
