Paper Abstract

A dual-waveband infrared re-imaging system has been designed with less lens number and short system length. The properties of re-imaging system to correct chromatic aberration have been researched. The main parameters of this system include F number, focal length, diameter, dual waveband, and imaging plane size are 2,000 mm, 200 mm, 3-5 μm /8-12 μm, and 9.3 mm × 12.4 mm, respectively. After design the average modulation value of all fields of view is 0.60 at 10lp/mm, and the difference between limited diffractive system and actual system is less than 0.3. The ray aberration has been corrected at the center wavelength 5 μm. The focal length varies with wavelength around 400 mm, and gets 400 mm exactly at 4 μm and 10 μm.
