Spherical Lenses

Convex Concave High Precision Spherical Lenses

Singlet lens is a lens consisting of a pure single element, which can be considered as the fundamental element of developing optical systems. Based on optical engineers’ design, multiple singlet lenses might be utilized within an optical system with other optics.

Spherical Lens Definition

Spherical lens is the reflective surface of a part of the sphere. The surface may be either convex or concave. Conical lens has a reflecting surface that bulges inward and it reflects light inward. Convex sphere lens has a reflective surface that bulges toward the light source and it reflects light outwards. Substrate materials of spherical lens include all kinds of optical glass, UV fused quartz, IR fused quartz and crystal materials such as calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), germanium (Ge), silicon (Si), etc., and it is provided with various kinds of optical filming such as anti-reflective film, highly reflective film, beam splitting film, metal film, etc. The wide band anti-reflective film can apply to ultraviolet, visible, near-infrared and mid-infrared band.
