Optical lenses are made based on the principles of light refraction. Lenses are optical components made of transparent materials (such as glass or crystal). A lens is a refracting device with refracti...

Basic Principles of Optical MirrorsOptical mirrors are optical components that use the principle of light reflection to change the direction of light propagation. They have a wide range of application...

An optical window is a flat optical transparent plate, usually designed to achieve maximum transmission and minimal reflection and absorption within a specific wavelength range. These are typically us...

Optical Filters: Functioning FiltersFilters are made of plastic or glass and special dyes. A red filter only allows red light to pass through; similarly, for other colors. The refractive index of the ...

Principle of Optical Axis Alignment in Optical Cemented LensesIn the process of optical cementing lenses, whether resin cementing method or optical cementing method is used, it must be centered to ens...
