Abstract
An optical lens system includes, in order from a magnified side to a minified side, a first lens group of positive refractive power and a second lens group of positive refractive power. The first lens group includes a first lens and a second lens, and the second lens group includes a third lens and a fourth lens. One of the third lens and the fourth lens includes one aspheric surface, and each of the lenses in the optical lens system is a singlet lens. The optical lens satisfies a condition of TE>94%, where TEdenotes an overall transmittance of all of the lenses in the optical lens system measured at a wavelength of 400 nm.
