Abstract[English]
The present invention relates to the technical field of optical lenses, and in particular to a projection lens. The projection lens comprises a lens group I, an aperture and a lens group II which are arranged in a direction from a magnification side to a reduction side, wherein the lens group I comprises two lenses, and the lens group II comprises four lenses. The projection lens in the present invention adopts few lenses, has a simple and compact structure and small occupied space, can meet miniaturization development requirements, and has low costs, good mass productivity and good imaging quality.[French]
La présente invention concerne le domaine technique des lentilles optiques, et en particulier un objectif de projection. L'objectif de projection comporte un groupe de lentilles I, une ouverture et un groupe de lentilles II qui sont agencés dans un sens allant d'un côté grossissement à un côté réduction, le groupe de lentilles I comprenant deux lentilles, et le groupe de lentilles II comprenant quatre lentilles. L'objectif de projection selon la présente invention utilise peu de lentilles, présente une structure simple et compacte, occupe peu d'espace, peut satisfaire aux exigences de développement de miniaturisation, engendre de faibles coûts, dispose d'une bonne capacité à être produit en masse et offre une bonne qualité d'imagerie.[Chinese]
