Providing a laser interferometer measurement service

API to enter the Chinese market in 2000, although later entered, but after careful study of the advantages and disadvantages of the former, weaknesses. Combined with laser interferometry and photoelectric autocollimator technology: not only for the final evaluation of the accuracy can also be used to adjust the machine installation greatly improve the measurement efficiency and reduce machine time subjects the highest measurement accuracy: 0.5 ppm (standard) 0.25 ppm (Precision type) to improve the accuracy of the actual measurement principle and reduce the difficulty of the special nature of the use of portable laser emission production process determines the laser has a light that does not have: a good color: ordinary light photons emitted in the frequency of each not the same, so with a variety of colors. The same individual photon emission frequency of the laser, and therefore is the best monochrome laser light source. Monochrome laser characteristics in spectroscopy and optical measurements also been widely used, has become an important means of precision measurement. 2 coherence is good: stimulated emission due to the photons in phase are consistent mode selection effect coupled resonator so that each point of the laser beam cross section has a fixed phase relationship between, so good space laser of coherence . Laser provides us with the best source of coherent light. It is because of the advent of the laser, that prompted the rapid development of coherent technology to obtain holographic technology was able to achieve. 3 good direction: the divergence angle of the laser beam is very small, almost the only light spot diameter of about 1 km, a parallel laser irradiation to form the moon. The ordinary light emitted from the light shooting in all directions, in order to ordinary light together in one direction often used condensing means, but even the best searchlight, as will its light onto the moon, the spot diameter will be extended to 1000 km. In addition, the geometrical optics shows that the smaller the better parallel beam obtained by the focus spot size, coupled with the laser color is good, no dispersion aberration by the focused light spot size further reduced, up to micron or less and even cells or molecules can be used as cutting fine "scalpel." 4 high brightness: the brightness of the laser light source than ordinary times higher than 1012-1019, is currently the brightest light, strong laser can even generate millions of degrees hot. High-energy laser is one of the most valuable basic features. The use of high-energy laser so that the laser can also be used in laser processing industry and national defense and so on.
