Ultra-wide-angle door sight glass optical system
The invention discloses an ultra-wide-angle door sight glass optical system comprising a concave bowl-shaped negative lens, a plano-concave symmetrical large-view-field lens group and a symmetrical positive lens; the front side of the concave bowl-shaped negative lens has a convex cambered surface and the rear side of the concave bowl-shaped negative lens has a concave cambered surface; the plano-concave symmetrical large-view-field lens group is arranged on the rear side of the concave bowl-shaped negative lens and comprises two plano-concave lenses which are symmetrically arranged; the symmetrical positive lens is arranged on the rear side of the front-end negative lens assembly, and the front side and the rear side of the symmetrical positive lens are provided with symmetrical convex cambered surfaces; and the rear side of the symmetrical positive lens is an imaging surface. On the basis of the inverted Galileo telescope design principle, a wide view field is provided for an observer, and by means of an ultra-wide-angle lens design method and a symmetrical lens design, the distortion problem is solved; the angle of view reaches 160 degrees, and the wide observation range can be achieved.
本发明公开了一种超广角门窥镜光学系统，包括：凹形碗状负透镜，凹形碗状负透镜的前侧具有外凸的弧面，后侧具有内凹的弧面；平凹对称型大视场透镜组，设置于凹形碗状负透镜的后侧，包括两片对称设置的平凹透镜；对称型正透镜，对称型正透镜设置于前端负透镜组件的后侧，对称型正透镜的前后侧具有对称外凸的弧面；对称型正透镜的后侧为成像面。本发明基于倒置伽利略望远镜设计原理，为观察者提供一个较宽的视场，借助超广角镜头设计方法，采用对称式镜头设计，解决畸变问题；视场角达到160度，能够有较大的观察范围。
