Laser refers to the product of stimulated emission light amplification, it has a monochrome, collimation, coherence and high energy density and other characteristics. It is because of the superior characteristics of laser, people will be widely used in human life in all aspects, such as printing, welding, cutting, communication, storage, etc., can be said that the blue laser for human production and life brought a qualitative leap. However, at the same time, the laser has also brought a lot of security to the human problem.
Metal marking machine is mainly used in laser marking processing, but the laser marking a wide range of metal materials can be marked processing is usually selected fiber laser matching marking equipment, such as carbon dioxide laser marking device is Can not be processed on the metal marking, the reason why there will be such a reason, with its own wavelength and its own characteristics of the decision. Fiber lasers due to the use of optical fiber transmission, and industrial machinery control flexible integration of higher, free from space or location factors, more able to achieve semi-automatic, automated, intelligent direction, the expansion of space is greater, while fiber green laser pointer almost No maintenance, power stability, good beam quality, long-term application cost-effective, easy to use, no need to replace any other accessories.
Static laser energy spectrum is a stable spatial distribution. Mainly applicable to micron-scale particles of the test, after the improvement can also be extended to tens of nanometers measurement. The dynamic laser analyzes the size of the nanoparticles by detecting the dynamic light scattering signals of one or two scattering angles according to the speed of the grain Brownian motion, and the energy spectrum changes with time. The dynamic light scattering principle of the particle size analyzer is only applicable to nano-scale particles. Transparent settlement usually refers to the laser particle size analyzer refers to the principle of diffraction and scattering particle size analyzer, light through the settlement instrument, based on the principle of Stokes settlement law rather than high power laser diffraction / scattering principle, so this instrument can not be called Laser particle size analyzer.
With the rapid development of laser application technology, many of the traditional manufacturing industry, the introduction of laser technology for products for enterprises to bring technological innovation and new impetus, but many companies do not do laser product safety certification preparation, for laser Of the hazards, the level of laser safety, the evaluation criteria and the national market for laser safety requirements are relatively unfamiliar. Mainly in the following areas: R & D design, production and processing personnel do not have the experience of laser work; corporate norms did not establish a sound laser safety requirements; personnel and facilities of laser safety protection is not in place.
The application of the laser in the client often requires the combination of laser shield, fiber, robot, exhaust and other ancillary equipment to form a complex red laser pointer processing production system. The systematic safety assessment of these laser processing systems is often overlooked by the enterprise. Compared to the safety requirements of a single laser device, the safety assessment of the laser processing system is much more complex: not only requires the laser light source to be designed to meet laser safety requirements, but also to require all parts of the system to work together to prevent all possible hazards ; Not only to consider the laser beam-related hazards, but also to consider electrical hazards, mechanical hazards, chemical hazards, ionizing radiation hazards, toxic and hazardous substances hazards.
The person in charge of laser safety refers to the personnel designated by the enterprise who have sufficient knowledge of laser safety and can assess and control the laser hazard for the enterprise. The person in charge of laser safety needs to be involved in all activities that may cause laser hazards, and to manage the laser pen safety issues within the enterprise. Enterprises need to introduce the laser safety in the management system and organizational structure, giving the laser safety responsible person full power, the formation of internal focus on laser safety system.
