The flip-over green laser pointer are also known as speech aids

Cooling water quality is better too serious, faucets aluminum oxide, used for a period of time necessary to periodically clean the pumps and pipes.
 Water protection in the dirt, otherwise caused by the laser tube to burst or cold water to head off. The suction device should regularly check to clear, the fan duct to clean up or a lot of smoke dust did not break out, serious pollution of the lens and the laser tube, easy oxidation caused by exposure to bad machinery and electronics parts. Focusing mirror and the mirror to check a frame fever, the lens surface discoloration rust; stripping cracking belong to the object you want to replace, in particular, many customers with a large air pump and air compressor. Ordinary and extended electronic functions are adopted in the second-generation  green laser pointer .
So that the focusing lens quickly stagnant water, it must be time to check the lens (laser tube optical) cleaning of the optical system and the quality is good or bad. Machine working environment can not be too bad if the ambient temperature is above 30 degrees, lower than 18 degrees, too much dust, air pollution is a serious, serious damage to such a machine, the failure rate is rising; all electrical accessories is very easy in the wet environment problem. So remind customers to improve the working environment and regular maintenance of the machine. On the basis of an extension of other electronic functions, the second-generation  green laser pointer  are developed.The typical products of the second generation of  green laser pointer  can be used to flip over PPT.  Electricity grid power to match. The device, part of the power distribution and point of contact to well (fan, water-cooled machine, laser machine, laser power, the computer to be an independent power supply) Laser tube current to be reasonable, not a long period of 90-100 intensity; to rationalize the application of laser and conservation of the laser energy; optical system to clean and correct, otherwise the resulting laser tube to premature aging and rupture, so the laser machines work time should be adjusted to 50-60%.
 The flip-over  green laser pointer  are also known as speech aids, or speech assistants, etc..  Then according to the material to adjust the pace of work, is the laser tube the best working conditions. Bottom and raw materials to be smooth, otherwise caused by the focal length is inconsistent in some places cut do not wear, so take light intensity increased, also resulting in the rapid aging of the laser tube. 10 laser power dissipation to be smooth, or more than 50% of the operating current tune the temperature rise is high, so that the laser power increased failure rate. Like the TM series machine side door to take down the power supply heat issue directly distributed out.
