Principle: According to the energy level transition mechanism of the molecular absorption spectrum and fluorescence spectrum of substances, a substance with the ability to absorb photons can emit light that is longer than the excitation light in an instant under specific wavelength light (such as ultraviolet light), that is, fluorescence. The relationship between fluorescence intensity and [...]
Applications of Infrared Up-conversion Materials in Anti-counterfeiting and Trace Indentifying Technology Key words: infrared up-conversion; changing infrared to visible light; anti-counterfeiting technology. 1. Principle The general light excitation process follows the Stoke-Lomoli rule, that is, the maximum wavelength of the emitted spectrum of the excited substance moves in the long-wave direction relative to the maximum wavelength [...]
The 405nm blue-violet dot laser uses different power laser diodes and optical lens with different parameters to produce circular or elliptical spots. The beam divergence and spot size are also different. The output power can also be adjusted according to different usage requirements. The modules can be customized according to the specific use of clients. The [...]
▲This section for the fixed-focus laser module, not around the laser head of the focusing head, the glass lens light fine. ▲K9 high through industrial grade window film, dust and water. Played spot uniform, light spot is small, the light is good. Glass column-line lens high-precision, fine line to 1.5mm (effective distance [...]
