Title (EN) OPTICAL LENS FIXING DEVICE AND OPTICAL PROJECTION SYSTEM
(FR) DISPOSITIF DE FIXATION DE LENTILLE OPTIQUE ET SYSTÈME DE PROJECTION OPTIQUE
(ZH) 光学镜片固定装置及光学投影系统
Abstract:
(EN) The utility model provides an optical lens fixing device, comprising an optical lens support for supporting an optical lens and a pressing plate protection sleeve assembly for fixing the optical lens on the optical lens support. The pressing plate protection sleeve assembly comprises a protection sleeve and a pressing plate; the protection sleeve is fixed on the optical lens support; an accommodating recess is provided in the protection sleeve; the pressing plate is fixed in the accommodating recess; and the pressing plate and the protection sleeve together clamp the lens. The utility model also provides an optical projection system. Compared with the prior art, the optical lens fixing device and the optical projection system of the utility model have good optical properties, and high reliability and stability.
(FR) L'invention a trait à un dispositif de fixation de lentille optique qui comprend un support de lentille optique servant à porter une lentille optique, et un ensemble manchon de protection et plaque de pression permettant de fixer la lentille optique sur le support de lentille optique. L'ensemble manchon de protection et plaque de pression comporte un manchon de protection et une plaque de pression. Le manchon de protection est fixé sur ce support de lentille optique. Un évidement de réception est pratiqué dans ledit manchon de protection. La plaque de pression est fixée dans l'évidement de réception. Cette plaque de pression et ce manchon de protection serrent ensemble la lentille. L'invention concerne également un système de projection optique. Par rapport à l'état de la technique, le dispositif de fixation de lentille optique et le système de projection optique de l'invention présentent de bonnes propriétés optiques ainsi qu'une fiabilité et une stabilité élevées.
(ZH) 本实用新型提供了一种光学镜片固定装置,包括用于支撑光学镜片的光学镜片支架和将光学镜片固定于所述光学镜片支架的压片护套组件,所述压片护套组件包括护套和压片,所述护套固定在所述光学镜片支架上,所述护套内开设收容凹槽,所述压片固定于所述收容凹槽内且所述压片和所述护套共同夹持所述镜片。本实用新型还提供一种光学投影系统。与现有技术相比,本实用新型的光学镜片固定装置及光学投影系统光学性能好、可靠性及稳定性高。
