A meniscus lens is defined as a crescent shaped lens consisting of two spheres with small radius of curvature and little difference in values. The fo

The Doveprism is a kind of spinner like. When light passes through this prism, the image is reversed 180. In addition, when the prism is rotated on it

Two reflecting surfaces perpendicular to each other are called ridge surfaces, and a prism with ridge surfaces is called ridge prisms. Because of thei

Triple-glued lenses are made by gluing one lens with a low refractive index and two lenses with a high refractive index. Since these lenses are design

A plano-convex lens has a convex surface and a flat surface with a positive focal length. In order to reduce spherical aberration, when a plano-convex

The double convex lens is machined by two identical spheres. Since the two spheres have the same radius, it can effectively eliminate the distortion,

Double concave lens is similar to plano-concave lens, the focal length is negative, the parallel incident light diverges outwards, and the two side cu

Proprism is an isosceles rectangular prism shaped by glass block, with the end plane facing the right Angle. In use, the light enters through the larg

A plano-concave lens is one side spherical, one side planar, and thinner in the middle than on both sides. They have a negative focal length and are u
