What do we mean by a spherical lens? 1、 Basic concepts Definition: A mirror whose reflective surface is a part of a spherical surface is

In optical devices, a piece of glass or other transparent material that is cut at precise angles and planes and can be used to analyze

Optical filters are used to “attenuate or enhance the image.”. Optical filters can also reflect unique wavelengths, dividing images into two identical images or transmitting

Spherical lenses achieve different imaging purposes by changing the spherical radius of the lens, which is difficult to process when the focal length is too

In order to eliminate the polarization effect caused by oblique incidence of light, a design method of depolarizing prism based on Brewster condition is introduced.

We can provide a large number of customized infrared IR lenses and components for focusing, collimating, and collecting light in the Near Infrared (NIR), Short

Flat concave lens: One side is concave and the other side is planar, with a negative focal length. Typically used for beam collimation, increasing (decreasing)

A pentagonal prism is a pentagonal prism with four polished surfaces, two of which are reflective surfaces, and the other two are incident and outgoing

Dowell prism has a very unique performance – if you observe through the prism and rotate around the longitudinal axis, the resulting image rotation angle

What is a pyramid prism? The pyramid prism, also known as the Paul prism, is an optical element used in optical instruments and is a
