Flat concave cylindrical lens is an optical product, which forms a divergent linear virtual image, which is used to control the size of only one

Flat concave cylindrical lens is an optical product, which forms a divergent linear virtual image, which is used to control the size of only one

Introduction to flat convex cylindrical mirror The plane convex cylindrical lens forms a linear image, which is used to control the size of only one

Introduction of cylindrical lens Cylindrical mirror is an aspherical lens, which can effectively reduce spherical aberration and chromatic aberration. It is divided into flat convex

Ball lens is an important optical element, which is mainly made of optical glass and other materials. It is used for the coupling between optical

Ordinary achromatic lens refers to a lens group that corrects the color difference of light of three wavelengths (blue light, green light and red light).

A lens is made by grinding a transparent material such as glass into a circular sheet so that both surfaces are curved or one side
One side of the meniscus lens is convex and one side is concave. It can be a convergent lens or a divergent lens, which is
The double concave lens is similar to the flat concave lens. The focal length is negative, but the light incident in parallel diverges outward. The

The biconvex lens is a biconvex lens sheet, which comprises an incident surface and an emitting surface. It is characterized in that the focal length

They have a negative focal length and are used to diverge a beam of parallel light. A flat concave lens has a spherical surface on
