green laser pointer factory focuses on technical reform

The laser has good monochromaticity, while limiting the direction of the laser, so we decided to laser coherence; resonant cavity can be adjusted to achieve laser frequency stabilization for example Lamb dip frequency stabilization and saturation absorption frequency stabilization principle.

 A grating spectrometer of the basic principles (grating spectrometer of the basic principles of grating spectral theory, spectroscopy of the overall design and spectral measurement principle, etc.); 1 grating spectrometer of the basic principle: the diffraction grating is a grating spectrometer core dispersion device, it recording medium to use more photoresist, usually with lasers as light sources, can produce thousands of pairs per millimeter grating spatial frequency, and through exposure and developing, directly type the sinusoidal transmission grating relief.This    green laser pointer    factory focuses on technical reform. The spacing of the adjacent groove grating constant d is called, usually per mm groove density of hundreds to hundreds of thousands of engraved lines parallel to the direction and the spectrometer slit. When the incident light parallel to a plane diffraction grating, so that the diffraction light through a lens, the lens focal plane to be in the grating diffraction of Fraunhofer Vladimir images in Figure 1. If the light is parallel to the grating notch of quasi-monochromatic slit light source, the diffraction pattern of some discrete bright lines (light stripes). At the grating surface normal incident light stripes on the same side of the equation to take a positive sign; the opposite side when you get a negative number.The    50mW blue violet laser pointer  factory focuses on developing new products. Each slit grating on the single-slit diffraction in the θ direction of light vibration to generate a point P, N crack generated in the P N-point amplitude of vibration of light the same, their coherent superposition of point P determines the intensity, the grating single-slit diffraction is a multi-slit diffraction and the total effect. Obscure is simply to meet a grating can be split, because every groove grating diffraction results. As the diffraction of light through the grating to the light at different wavelengths of light diffraction out along different directions. Each groove diffraction of light interference between each other.The product shape of this  100mW green laser pointer   company is novel and beautiful. Different wavelengths of light interference maxima appear in a different direction, and thus compound after the dispersion of light through the grating formed spectrum. (A) the plane grating equation reflective diffraction grating is engraved in a series of high-precision plane width but spaced notches formed by the grating element is generally engraved on a millimeter to tens of thousands of the notch , 600mm × 400mm. Parts, the general grating inscribed in a millimeter to tens of thousands of the notch, depicts an area of up to 600mm × 400mm. When the incident light beam parallel to the grating on the compound, as shown in Figure 12-7, when the incident light beam parallel to the grating on the compound, which according to the wavelength in the grating can be decomposed into spectral space, which is due to multi-slit diffraction and interference results. Products of this   200mW green Laser Pointer   company are well received by their excellent performance at home and abroad.Grating spectrum, its position is a multi-line slit diffraction pattern which is due to multi-slit diffraction and interference results. Grating spectrum, the largest sample of the main conditions of the decision. The largest sample of the main conditions of the decision. Level meeting to adopt the grating spectrum must be observed. This is in order to obtain a wavelength spectrum of the m-level meeting to adopt the grating must be followed.
