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 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 light module includes a first light source. The first light source includes a first light-emitting element and a first lens element. The first light-emitting element includes a first light-emitting chip for emitting a first light beam and a wavelength conversion material located on the first light-emitting chip for transferring parts of the first light beam to a second light beam. The first lens element faces the first light-emitting element and is located on a transmission path of the first light beam and a transmission path of the second light beam, and the first lens element includes an optical filter for filtering off the first light beam and being passed by the second light beam.

Abstract: A zoom lens includes a first lens group with a negative refractive power, a second lens group with a positive refractive power, and an aperture stop disposed in and movable with the second lens group. Each of the first lens group and the second lens group moves individually. The zoom lens further includes a doublet lens disposed on a first side of the aperture stop and between the first lens group and the aperture stop, and at most two lenses including at least one aspheric lens are disposed on a second side of the aperture stop.
