Infrared principle
1. Infrared Definition
In nature, any object with a temperature above absolute zero (-273℃) can emit electromagnetic waves. Infrared is the most widespread form of electromagnetic waves in nature, it is a kind of energy, and this energy is invisible to our naked eyes. Any object in the conventional environment will produce its own molecules and atoms irregular movement, and constantly radiate thermal infrared energy.
2. Infrared band range
The light waves emitted by the sun are also called electromagnetic waves. Visible light is an electromagnetic wave that can be felt by the human eye. After being refracted by a prism, seven colors of red, orange, yellow, green, cyan, blue, and purple can be seen.
Infrared light is part of these electromagnetic waves, which together with visible light, ultraviolet light, X -rays, gamma rays and radio waves make up a complete continuum of the electromagnetic spectrum.
As shown above, electromagnetic radiation with wavelengths ranging from 0.xn--76m-yyc to 1000μm is called infrared radiation.
Infrared optical lens:
The infrared optical lens is usually composed of a group of lenses, which can receive various infrared final focal length to the infrared detector, photoelectric conversion processing.
The germanium crystal with a refractive index of 4 is the most used in infrared Oplens optical lenses
, which is suitable for the 2-25μm band . Si with refractive index of 3 is commonly used in the band of 1-6μm. The heat-resistant shock of the missile fairing is optimized to use the hot-pressed MgF2 andZnS.
