New Role Of Burning Tool High Power Laser

Post on: May 23,2019
Blue laser pointer is actually an ideal tool for burning stuffs, with adjusted the laser beam focus. The strong powered laser can set fire on matches, paper or other imflammable objects just like a lighter can do but with the burning laser, you'll be able to light the stuffs at certain distance without getting closed.With countless reports critized on the high power laser pointer hazard to human bodys. I would insist that anything that can burn up a fire is dangerous at the same degree, a normal lighter or knife also do harm to humans but that don't mean people should not use these tools. Great power tools brings greater danger, proper operation is the most important thing before you use a burning tool.In fact, class 3 or 4 laser pointers only be dangerous when the shining laser lights shoot or reflect towards human body, especially the eyes. The higher power, the exposure time to cause damage will be shorter. Avoiding laser beam just like avoiding the fire burns you, that's enough to keep you safe, a professional laser goggle will be a plus to keep your eyes safe if you need to stare at the shining laser for a long time.Class 4 laser pointers are the ideal choices to used as a burning tool. Compared with green or red laser pointers, blue laser beam is dim but more powerful to able get stuffs burned.

Laser Pointer FAQ(3)

Post on: April 28,2019
How much is laser pointer speed?Ordinary light propagation speed in the air is 300,000 meters per second. Laser propagation velocity in air is 300,000,000 meters per second. Laser propagation velocity in the air is 3/4 of vacuum. Laser propagation velocity in the glass is 2/3 of vacuum.Safety measures of laser pointer operation:● Laser pointer at room temperature can up to the brightest begin using. The continuous lighting should not exceed 30 seconds.● Laser is harmful to eyes. Do not air at eyes illumination. Please wear appropriate laser safety goggles indoors or close to the blue laser pointer. Avoid direct pointing of laser pointer at eyes. Laser irradiation up 30mW cannot face the human body, in order to avoid accidental injury.● Keep laser pointer away from children, and prevent danger from the improper use of laser pointer. Remove the battery and saved when laser pointer is not in use.● Please pay attention to battery or replace battery if found severely reduce of brightness of laser beam.● Do not continuous light laser too long (especially green laser), in summer it is best no more than 30 seconds. Please immediately stop use until it is completely cool if you feel laser pointer is hot. The best time to use high powered laser pointers in controlled time of 1 minute, turn off 5 minutes for cooling and then open. It can prevent excessive aging of laser pointer, or laser diode damage caused by overheating. These indications can protect laser pointers a longer serving lifetime.

Laser Pointer FAQ(2)

Post on: April 23,2019
Why laser diode and crystal of laser pointer can be easily burnt out?Long working hours is a key point which can cause laser diode burnt out. Due to long working hours, laser temperature increases with the increase of working hours, resulting in damage to the laser diode and crystal.When laser pointers require preheating? Laser pointer crystal is composed of yttrium vanadate crystals (YVO4), of which yttrium vanadate crystals are very sensitive to temperature, stable operating temperature at 20 ° -30 °, yttrium vanadate crystals stimulate operating temperature 20 °. When the outside temperature is below 20 °, yttrium vanadate crystal would be difficult to start. The lower the ambient temperature, the longer startup time will be spent on laser pointers.Why green laser pointer power will decay at a high temperature?Green laser pointer consists of 808nm laser diode and crystal, operating temperature of 25°, laser diode wavelength 808nm±2nm. When operating temperature is up 25 °, laser diode wavelength will be shorter, thus laser power reduces along with wavelength change. The longer the operation time of laser pointer, the higher the temperature and the power will also decay.

Laser Pointer FAQ (1)

Post on: April 14,2019
What is the difference between red and green laser pointer?Wavelength difference. Red laser wavelength is between 635nm to 780nm. Green laser wavelength is 515nm, 520nm and 532nm.Different light emitting mode. Red laser pointer emit light directly from laser diode, without extract devices. It emits bright light directly from red laser diode. 532nm green laser light is emitting from 808nm laser diode pump crystal.Why blue violet laser pointer light spot is very weak?According to the principle of lasers, in case of same power, the shorter wavelength laser pointer can emit brighter light than longer wavelength one. However, the perspective of 532nm wavelength light is more easily absorbed and more sensitive, light emitting from 405nm blue violet laser looks much weaker to human eyes.Why red laser beam is not as visible as green laser?Shorter wavelength laser has great loss in the atmosphere, thus green laser pointer is more easily visible than red laser beam. Green laser light is more easily absorbed by dust in the air, green laser pointer is more easily reflective, and thus beam of green laser pointer is much more visible than red laser pointer.How long can green laser pointer can be lighted?The continuous lighting time of green laser pointers will vary depending on output power. Portable green laser can be lighted within 10 seconds under formal working temperature of (25 °). If operating time is extended, the output power might be increased in attenuation, until not bright. Long operation time can destroy laser diode and crystal, or even burn out laser diode. Industrial alignment laser can be operated 24 hours continuously a day under room temperature and correct cooling system. The portion of alignment laser should be fixed in operation.

Drive birds without hurting them

Vultures are protected species, and the USDA-certified strategy is to intimidate it and leave them alone without harming them.The US Department of Agriculture estimates that approximately 300 vultures live in the Granville and Denison campuses. And in addition to disrupting HVAC projects and different machines, it can also cause damage to the roof.According to some sources, the vulture caused a loss of about 50,000 dollars in 12 months.After several weeks of investigations, the US Department of Agriculture decided to deploy three teams, using laser lights, fireworks and electronic windsocks to further demonstrate the unwelcome nature of the environment. Lasers have played a big role in this task.They are smart, hospitable animals that neatly respond to tactics that they think are unpopular. You can also directly laser instructions on birds. We found that green pointers are more practical than red pointers.

About the high power blue laser pointer

Post on: March 29,2019
The blue laser pointer is actually the ideal tool for burning items. By adjusting the focal length of the laser beam, a powerful laser can ignite matches, paper or other flammable objects, just like a lighter can do, but with a burning laser, you will It is something that can light a certain distance without being turned off. There are countless reports criticizing the dangers of high-power laser pointers on the human body. I insist that anything that can burn a fire is at the same level of danger. A normal lighter or knife is also harmful to humans, but this does not mean that people should not use it. These tools, great power tools pose a greater danger, and the right thing to do is the most important thing before using a burning tool.In fact, a level 3 or 4 laser pointer is dangerous when the laser is illuminated or reflected into the human body, especially the eyes. The higher the power, the shorter the exposure time that causes damage. Avoiding a laser beam like a flame will make you feel safe. As long as you need to stare at the shiny laser for a long time, professional laser goggles can keep your eyes safe.Class 4 laser pointers are ideal for use as a combustion tool. Compared to a green or red laser pointer, the blue laser beam is dim but more powerful and can burn objects.

About the structure of Laser Pointer Pens
