The material the workshop needs from the warehouse of green laser pointer

However, even in sunny weather conditions, light intensity and the transmission direction of the radiation will fluctuate, this fluctuation is a popular molecules, aerosol particles and air turbulence caused by the inhomogeneity. Such as laser range finder even after years of development, technology, engineering, when there are many problems to be solved. If these problems are not addressed, will be brought to the volume of manufacturing difficulties, while production costs will increase and the promotion of the laser range finder to bring some adverse effects. Only the complete and signed material inquisition sheet of green laser pointer can get the material the workshop needs from the warehouse of green laser pointer.
The issue comes from the semiconductor laser ranging system. Narrow pulse laser alignment system as a subsystem of a whole range finder, laser range finder is an important part, both from the improved system stability and efficiency, or from industrial production to achieve the system in terms of miniaturization, launch the design alignment are key. Therefore, the semiconductor laser ranging system, part of the launch of alignment design is very meaningful. 1940s, due to electromagnetic theory and technology, while the urgent need because of the war, the British first developed the radar. Its appearance is a historic breakthrough ranging technology. It allows people the first time at a fixed point in different directions on the rapid determination of the instantaneous distance of the target in the battle of Germany played a key role.  led flash light of different specifications can meet different needs of different customers.
But it also has some shortcomings, the relatively long wavelength emission of electromagnetic waves, early radar beam is wider, lower spatial resolution, only applies to the monotonous background of target detection, but also susceptible to interference and attacks with serious shortcomings. 1960s appeared laser technology has greatly promoted the scientific, technical, economic and social development. Laser because of its good directivity, monochromaticity, high brightness, and soon to be used in distance. Although only a band with the radar compared to the change, but it has greatly expanded its ranging capability, such as accurately measuring the distance from Earth to the Moon. Laser ranging in the following advantages: high precision ranging, Damien level can be even higher; laser beam divergence angle is small, strong directional; anti-electromagnetic interference capability, able to adapt to battlefield conditions are very complex electromagnetic environment ; of microwave radar stealth targets, while the laser is usually not stealth, stealth target distance relative improvement. The expert group will start the manufacture supervision of green laser pointer in the workshop tomorrow.
Since the 1960s, the first since the advent of the laser range finder, laser ranging technology is developing rapidly. Until now, laser rangefinder has been developed to the third generation: the first material for the work on behalf of the ruby laser rangefinder; second generation in Nd: YAG working material for the laser range finder; third behalf of the human eye safe laser rangefinder. The first generation of laser range finder came in the early 1960s, working material for the ruby laser, wavelength of 0.69μm. Early 1961, Hughes Aircraft Company Culver City, Malibu, and the two groups, respectively, created the first active laser ranging system, and operate the [2]. As the launch of the red light, easy to expose, plus the low efficiency of the system, size, power consumption than other shortcomings, will soon be
