Shortwave pass filter: cutting off the high frequency is the shortwave pass filter. Usually, it has two meanings. One is to filter out the light

The band-pass filter is a filter adjacent to the cut-off band on both sides of the transmission band of the spectral characteristic curve. According to

Right angle prisms are usually used to turn the optical path or deflect the image formed by the optical system by 90 °. According to

Pentagonal prism is one of the beam steering devices with fixed angle (90 °). It has two purposes: first, the outgoing light turns the incident

Two reflecting surfaces perpendicular to each other are called ridge surface, and the prism with ridge surface is called ridge prism. The ridge prism is

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).
