Abstract

An off-axis type refractive/diffractive Gregorian telescopic optical system without any aspherical element and center obscuration is presented in this paper. A binary optical element is used to correct aberrations and its size is reduced to 1/3 or 1/4 of the Schmidt corrector. Using OSLO SIX4.2 (Sinclair Optics Inc.) optical design software, an off-axis infrared refractive/diffractive hybrid telescopic system is designed with the parameters: aperture (phi) equals 120 mm, effective focal length f equals -1000 mm, wavelength (lambda) equals 4.3 micrometers , the field of view 2 degree(s) X 6 degree(s), resolution Res equals 50 um, modulation transfer function >= 0.4 when the spatial frequency v <EQ 10 cycles/mm.
