50 mw green laser sight
Red lasers are established and widely available in commercial products today; blue and green lasers are coming shortly. Developments in these compact blue and green lasers will enable a new generation of products capable of generating full color images. Green lasers are not only many times brighter and more complex than their lesser red siblings, they are also much more expensive as a result. The benefit to green lasers is not only the unique quality of the color but also the fact that pretty much any green laser from 5mW and up has a beam that is quite visible at night. Green Lasers are the brightest and most powerful lasers on the market. Green lasers are used for medical research in addition to hundreds of other applications.
Hence, green lasers are more visible than red lasers for great distances. Various fashion designs and colour options. As a result, green lasers are approximately 50 -100 times more receptive to dark-adapted eyes according to authoritative sources. This translates to them being visible at far greater range for the same power output. Indeed, 5 mW green lasers are already banned in the United Kingdom.

Unlike traditional red and blue lasers, green lasers are suitable for use while stargazing [because the light beam is easy to follow during low light conditions]. I put the laser to the test at Discovery Park and was amazed at the strength and brightness of the laser for pointing out objects in the distance. Our green lasers are so bright and powerful they can burn, slash and melt plastic or, if you are so inclined, light your smoke. The green lasers create a beam you can see for miles in dark conditions.
The smallest mass produced microchip laser crystals I know of are the CASIX DPM0101 hybrid vanadate-KTP module used in some green laser pointers: 1x1x2.5 mm. With cooling on all 4 sides, these may be capable of more than the small number of mW required for a pointer. Many DPSS laser pointers have special filters that block the infrared, but test for infrared output before being sure. They are much more complicated than standard red laser pointers, because laser diodes are not commonly available in this wavelength range. The green light is generated in an indirect process, beginning with a high-power (typically 100-300 mW) infrared AlGaAs laser diode operating at 808 nm.
Inexpensive laser pointers, in conjunction with a few other inexpensive devices, have been successfully used by hobbyists to produce high-quality holograms . They have also been used to blind security cameras. So use them wisely - laser pointers ARE NOT toys and should not be used in away to cause damage to people or property. This is why the AAA batteries used in green laser pointers wear out faster than when they are used in red laser pointers.
Infrared light cannot be seen by the human eye so the beam from these shoddy laser pointers is not as bright as it should be and is also very dangerous. These laser pointers have increased power output, and the FDA has been working to prevent the sale of these products. If you want the best green laser pointer you have found the place to buy it! We even have the cheapest green laser pointer with high quality design and function for all uses.
Of particular concern are high powered laser pointers emitting green wavelengths. The eye is more sensitive to green wavelengths and consequently lower powers are needed to provide the same level of brightness that would previously have been achieved using pointers emitting red wavelengths. If the pointer is kept on longer or continuously it may dim out, however, it will not be damaged because the control circuit will prevent current from rising to a harmful level. Cheep laser pointers have tons of perfectly harmless uses. Pet toys are already mentioned.
If police have reasonable grounds for suspecting a person is in possession of a hand held laser pointer in a public place, that person can be searched, the hand held laser confiscated and legal action taken. This can result in 2 years imprisonment or a fine of up to $5,500. The laser pointer is great for star gazing and teaching uses, but you can also give fun demonstrations. For example, a 125mW laser can easily pop dark balloons and cut black plastic bags! Compared to a red laser pointer, the green beam remains visible and penetrates the air much farther. Because of its particular spectrum you see the beam and not just the end dot.
Ashen's review of a piece of shite MP4 player , you'll definitely love what he's done with a green laser pointer. Oh yes, we're proud to announce that Dr. Hey, I just saw your post about laser pointers. I am actually a moderator ("Moderator") on laserpointerforums.com , apart from the red, green, yellow, and blue, there are just now, violet lasers pointer which sell for around $400-600. These red laser pointers can point a dot a hundred miles away and burn, cut and slash plastics as well like their green counterparts. They consistently outperform your average key chain 5mw laser pointer over 50x in terms of range, burning power and durability.
The green laser beam dot can be seen at much greater distances than with a red laser pointer. Green laser pointers are not a toy, should never be aimed at an aircraft, and should never be used by children. The light output from green lasers is extremely bright and can permanently damage the retina of a person's eye. I just learned that some people are selling quite cheap "laser pointers " via ebay, emitting green light at a power level of the order of 100 mW. Such a power level is of course well above what is reasonable for a laser pointer – about 1 mW should normally be enough.
I have had a technical problem with a green laser pointer after the period of manufacturer's guarantee and they offered to to give me a good rebate if I returned the item and bought an other one ! Where else do you see that ? A laser pointer is laser shaped like a pen that is designed to be portable and hand held. Laser pointers were originally used to project a dot or point from the beam that can be used to point out items or objects to an audience such as during a presentation. I did that to a web cam with my 5mW green laser pointer from thinkgeek (not the 10mW I did the review on) and the laser destroyed something in the optics. The camera still works, but the picture looks like a funky gray mosaic.
Used properly, laser pointers are quite safe. But used improperly or maliciously, they can be dangerous indeed. Remove pattern cap and it's a standard green laser pointer. Laser pointers are misused when they are directed at the eyes or treated as toys. The light energy from a laser pointer aimed into the eye can be more damaging than looking directly into the sun.
