ABSTRACT:
The present invention relates to a relay lens system, wherein all image aberrations are corrected. This permits modular use with no stand-alone lenses or lenses with great focal distance. The relay lens system comprises at least two subsystems, wherein at least one positive lens and at least one negative lens are placed in at least one subsystem near the intermediate image, and the refractive index N(+) of at least one positive lens and the refractive index N(-) of at least one negative lens and the total focal distance F(FLD) of the lenses of the subsystem near the intermediate image correspond to the following relations:
