摘要
A catadioptric zoom relay telescope with an aspherical primary mirror and only three movable lens elements focuses all wavelengths in a broad infrared bandwidth onto a common focal plane with substantially diffraction-limited imagery throughout a changing focal ratio (i.e., a zoom range) from less than f/1.5 to more than f/6.0.
