AN OPTICAL SYSTEM FOR INFRARED TWO-COLOR DETECTOR
适于红外双色探测的光学系统

A new optical system for infrared two-color detector was designed. It has a good performance for the dual band simulaneously. The wave front aberrations are less than one-fourth central wavelength, and the modulation transfer functions to are the diffraction limit. The system possesses higher transmitlance, compacted structures with fewer elements and lower requirements in manufacture.
