Prisms are usually cut and ground from a solid piece of glass, and then coated with reflective materials on all surfaces except for the two that connect to the focusing screen and viewfinder. This cre...

As is known to all, optical filter films can adjust the molecular structure by different colors, so as to change the refractive index of the material and adjust the light transmission rate. The absorp...

Optical windows are flat plates made of optically transparent material, designed to allow light into an optical instrument. They can also be used to protect a light source from an outside environment....

A very small lens is called a micro lens. They generally have a diameter of less than a millimeter (mm) and are often as small as 10 micrometers (µm). The first micro lenses were fabricated for use i...
