摘要： An optical lens system using ultraviolet for imaging 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 second lens group includes at least one cemented lens and at least one aspheric lens. The optical lens system satisfies the 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 and is equal to a product of respective internal transmittances of all of the lenses measured at a wavelength of 400 nm.

摘要： 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.

摘要： A projection lens system includes, in order from a magnified side to a reduced side, a first lens group of positive refractive power and a second lens group of positive refractive power. The second lens group includes at least one cemented lens and at least one aspheric surface. During focusing, the first lens group remains stationary, and the second lens group is movable in a direction of an optical axis.
