Evaporation deposition During evaporative deposition, the source material in the vacuum chamber is heated or bombarded by an electron beam and evaporates. The vapor condenses

With the rapid development of space technology, aerospace strategic weapons and microelectronics technology, more and more optical components are used in aerospace products. Radiation environment

The difference between laser lens and LED dual light lens is actually not big. The lower beam is the light source of LED, and the

“Soul germanium glass” of infrared thermal imager lens The infrared thermal imager receives the infrared radiation emitted by the object through the lens and reflects

Optical reflective films can generally be divided into two categories: metal reflective films and all dielectric reflective films. In addition, there is a metal dielectric

Antireflection film, also known as antireflection film, its main function is to reduce or eliminate the reflected light on the optical surface such as lens,

No matter the glasses made of inorganic or organic materials, in daily use, the friction with dust or gravel (silicon oxide) will cause lens wear

Glass can change the propagation direction of light and the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass can be used to

Common optical coating materials are as follows: 1. Magnesium fluoride Material features: colorless tetragonal powder with high purity. Using it to prepare optical coating can
