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: A fixed-focus lens includes an anti-radiation first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens arranged in order in a direction. An aperture stop is disposed between the first lens and the fourth lens. A ratio of a lens diameter of the first lens to an overall length is within a range of 0.4 to 0.5, where the overall length is an axial distance between an outer surface of the first lens and an outer surface of the seventh lens. Each of the first lens to the seventh lens is a spherical glass 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%.
