Spherical lens technology principle
Basic structure and optical properties
Spherical lenses refer to optical components with spherical surfaces on the front and back surfaces or a spherical surface plus a flat surface, and their radius of curvature remains constant. According to the different surface shapes, they can be divided into:
- Convex lens type: the center thickness is greater than the edge thickness
- Biconvex lens: both sides are convex
- Planoconvex lens: one side is flat and the other side is convex
- Convex lens (meniscus convex lens): the radius of curvature of the convex surface is smaller than the concave surface
- Concave lens type: the center thickness is smaller than the edge thickness
- Biconcave lens: both sides are concave
- Planoconcave lens: one side is flat and the other side is concave
- Convexconcave lens (meniscus concave lens): the radius of curvature of the concave surface is greater than the convex surface
Table: Common spherical lens types and characteristics
Lens type Optical power Aberration characteristics Typical applications
- Biconvex lens Positive Spherical aberration is obvious Imaging system, focusing system
- Planoconvex lens Positive Spherical aberration is small Collimation system, projection system
- Meniscus lens Can be positive or negative Astigmatism correction Complex optical system correction
- Achromatic cemented lens Customizable Chromatic aberration correction Precision imaging system
Technical features of aspheric lenses
Aberration correction capability: By adjusting the aspheric coefficient and the surface constant, the spherical aberration generated by the spherical lens can be eliminated
System simplification: A single aspheric lens can replace the combination of multiple spherical lenses to reduce the system volume and weight
Optical performance improvement: In the focusing and collimation system, it can maintain better wavefront quality
