Pinhole type door sight glass lens capable of achieving right-angle observation
The invention relates to the design of a visual door sight glass lens, in particular to a pinhole type door sight glass lens capable of being observed at a right angle, which not only can meet the requirement of distortion, but also can effectively solve the problem that outdoor conditions can be seen by turning at a right angle. Comprising a rotatable front reflector, light enters a lens group after sequentially passing through the front reflector and an aperture diaphragm, and the lens group sequentially comprises a first plano-concave lens, a first symmetric positive lens, a second symmetric positive lens, a second symmetric positive lens and a second plano-concave lens in the light incidence direction. Wherein the first plano-concave lens and the first symmetrical positive lens form a balsaming lens, and the second symmetrical positive lens and the second plano-concave lens form a balsaming lens. The symmetrical design concept is applied, the distortion influence is reduced, the aperture diaphragm is arranged in front, and the door sight glass with a large view field is designed as far as possible. Light rays are turned through the reflecting mirror or the rectangular prism, specific problems in actual life are solved, the structure is compact, aspheric design is not used, cost is low, and imaging quality is high.
本发明涉及一种可视门窥镜头设计，具体为一种可直角观察的针孔型门窥镜镜头，既能解决畸变的要求，又能有效解决可以直角拐弯看到室外的状况；包括可转动的前置反射镜，光线依次通过前置反射镜、孔径光阑后进入镜头组，所述镜头组从光线入射方向依次包括平凹透镜一、对称式正透镜一、对称式正透镜二、对称式正透镜二和平凹透镜二，其中平凹透镜一和对称式正透镜一形成胶合透镜，所述对称式正透镜二和平凹透镜二形成胶合透镜；运用对称性设计理念，减少畸变影响，孔径光阑前置，尽可能设计较大视场的门窥镜。通过反射镜或直角棱镜转折光线，解决实际生活中的具体问题，结构紧凑且没有用非球面设计，成本低且成像质量较高。
