    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(λ=400)>94%, where TE(λ=400) denotes an overall transmittance of all of the lenses in the optical lens system measured at a wavelength of 400 nm.

    Abstract: An optical lens includes a first lens group with a negative refractive power, an aperture stop, and a second lens group with a positive refractive power. The first lens group includes a first aspheric lens and a second aspheric lens. The optical lens satisfies the conditions: 3.5>RT1>2.5 and 3.5>RT2>2.6, where RT1 is a ratio of a maximum axial thickness to a minimum axial thickness within a clear aperture of the first aspheric lens, and RT2 is a ratio of a maximum axial thickness to a minimum axial thickness within a clear aperture of the second aspheric lens.
