Abstract: 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.

Abstract: An optical lens system includes, in order from a magnified side to a minified side, a first lens group and a second lens group. The first lens group of negative refractive power has at least one aspheric surface, and the second lens group of positive refractive power has at least one aspheric surface. Each of the lenses in the optical lens system is a singlet lens, and the condition: TE(λ=365)>70% is satisfied, where TE(λ=365) denotes an overall transmittance of all of the lenses in the optical lens system measured at a wavelength of 365 nm.

Abstract: An optical lens including a first lens group located between a magnified side and a minified side and a second lens group between the first lens group and the minified side is provided. The first lens group has a negative power and includes a first lens. The first lens is a plastic aspheric and meniscus lens. Besides, the first lens has a negative power and a convex surface facing the magnified side. The second lens group has a positive power and includes a second lens, a third lens having a negative power, and a fourth lens. Every two of the second, third, and fourth lenses have an air interval between these lenses. The Abbe number of each of at least three of the lenses is greater than 20. A material of at least one of the lenses is glass. At least one of the lenses is a spherical lens.

Abstract: The disclosure provides a projection lens including a first lens set and a second lens set disposed sequentially from a magnified side to a reduced side. The first lens set and the second lens set are separated by a minimum inner diameter of a lens barrel. The first lens set includes 4 to 6 spherical lenses, and a refractive power of the first lens set is negative. The second lens set includes 4 to 6 lenses, where one of the lenses is an aspheric lens, and a refractive power of the second lens set is positive. A transmittance of the projection lens at a wavelength of 365 nm is greater than or equal to 75%.
