We design an optical system of infrared target simulator for infrared optical testing system.A non-focal and back-focal systems were adopted.We use Zemax software to design and optimize the system.The optical system works at 8-12μm with a field of view of 12°,a focal length of 230.599 mm,an exit pupil distance of 600 mm and an exit pupil diameter of100 mm.The optical system has 9lenses.The lens with the largest diameter is 229.77 mm.The designed optical system almost achieves diffraction limit.MTF of full fields are more than0.39.80% energy is focused within 23 μm diffraction circle. The design meets the requirement.The system is good for infrared optical testing system.
