Diffractive Optical Elements (DOE)
Multi-line structured light DOE At present, there are 10 kinds of multi-line structured light DOE standard products available, and the design wavelengths are 520nm, 635nm, 650nm, 660nm. The specifications of the multi-line structured light DOE are 5 lines, 7 lines, 11 lines, 15 lines, 25 lines, 41 lines, and 65 lines. The maximum XY axis angle [...]
Laser Induced Fluorescence Analysis
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 [...]

The Relationship Between Laser Shape and Lens
After using various laser diodes and various lenses for research, repeated comparisons, and combined with our company's existing products. A conclusion is drawn that the shape of the light spot is mainly determined by the laser divergence angle of the laser diode and the light spot of the laser diode. It has little to do with the [...]
The Influence of Different Coating Methods on Laser Output Power
Among lasers, optical lenses play an important role. The excitation conditions of the laser are very simple. There are working materials, excitation energy, and resonant cavity to generate laser. However, the utilization and utilization rate of the laser at this time are very low. It needs to be processed by an optical mirror group to reach [...]
The role of photodiodes in laser diodes
Laser diode is a kind of light source semiconductor laser invented in the 1960s, also known as laser tube (Laser Diode)。LASER is an abbreviation of "Light Amplification by Stimulated Emission of Radiation", usually abbreviated as LD.Since it can produce light with exactly the same properties such as wavelength and phase, high coherence is its biggest feature 。Laser diodes [...]
