Laser pointers with 405 nanometers wavelength of light are also called blue violet laser pointers. Although it is rarely prefered to the green and red ones, it could be used for what others do, which also reflects the individual unique aesthetic taste. It is probably not as much preferred lasers as an astronomy laser pointer, because brighter colors would make an object more visible in the sky. However it comes down to all other uses such as pinpointing something on the large screen or on the blackboard.
Green laser pointers is now the world's most popular laser pointers, because the green light than red light 6 times more than red light beam significantly, while the price is much cheaper than the blue and yellow. Green pen is the wavelength of light emitted 500-550nm, the wavelength sensitivity of the coefficient table, as is the closest one wavelength. Green is undoubtedly efficient light source, the eye more easily identified. The green light sensitivity of the human eye is higher than a lot of red; the other is green light scattering in the atmosphere more than red light.
Red laser pointers, wavelength 630-670nm green laser pointer is more for longer. The first red pointer was released in the early 1980s. Nowadays, the red laser diode technology has been very mature. More durable, the price is much more cheaper than ever. More easily transmitted red light air, dust, water vapor, so the light path can be seen to need more power. 100 mW red laser pointers probably only about 20 milliwatts, and green. Do remember that red laser pointers are powerful since the light they emit is powerful when it hits a certain object and converges into a point.
Place to note
Now, more and more laser pointers and flashlights sold in the market are class IIIB with a power over 5mW. But when the laser directly penetrates into the eyes, there may be some damage. Especially to some high power laser pointers, diffuse light probably damage the eyes, the focus are more likely to ignite flammable materials. Therefore laser pointers are not a toy, not suitable for children. When operating high-power laser, wear special secure glasses would be safe, especially for the invisible laser. In a word, no matter how much power the laser power is, you need to avoid hitting into your eyes.

As one of your customers already said that Laser Comes in a \\\"302\\\" aluminum body NOT stainless steal as advertised but This thing is very POWERFUL indeed and everything else is correct even the white box\r\nwith \"GREEN LASER POINTER\" on it.

Just received this after waiting over 20 days. I paid extra for the 5-10 day shipping. The bad first: Comes in a \"302\" aluminum body NOT stainless steal as advertised, but no big deal. Now the GOOD: This thing is very POWERFUL!!! Probably the full 5000mw as long as it\'s FULLY CHARGED before using. Burns right through paper/cardboard regardless of color! Melts black plastic instantly! Unit gets very hot after a few minutes of heavy, sporadic use. Then, it no longer burns & it\'s \"off to the charger for the batteries\" I highly recommend this but only if using with EXTREME caution. NOT a toy!

I JUST GOT MY LASER TODAY AND I FIND MYSELF SIMPLY AMAZED AS TO ITS QUALITY AND POWER. I CAN LIGHT CIGGIES FROM FIVE FEET AWAY AND ALL I CAN SAY IS THIS IS A GOOD THING FOR YOUR $100.00 WELL WORTH THE INVESTMENT I OPTED FOR EXPRESS SHIPPING AND IT CAME A DAY LATE BUT THAT\'S OK. WELL WORTH THE WAIT.

Laser came very quickly. I was astonished how good and powerful the laser beam is. Indeed, it\'s recommended to use protecting googles while operating this. I\'m fully recommending this laser for so bargain price.

I was skeptical as well but having a long time fascination with lasers I went ahead and bought this one. Even from over 8 feet, I could etch into wood like I used to do with a magnifying lens, of course, I\'d need to practice doing it with precision from that distance. With well charged batteries, the burning is almost instant, I even lit my pipe with it just as fast as if I used a lighter and I smoke a moist pipe tobacco that isn\'t easy to light. I am absolutely impressed and I don\'t impress easily. Please use responsibly. Note, the batteries go in negative first (flat side.)

I was a bit weary of it at first because of bad reviews read else where. But this is truly awesome. The battery drains fast, but it also charge fairly quick. The beam is visible in rooms and extremely visible at night or in the dark. On a sunny day it isn\'t very visible but still very bright. It\'ll burn a match in a second, and everything else. it has difficulty burning white objects, but while smoke anything dark in seconds. Definitely worth the money. Not 5w but is strong enough. The beam is squarish the further away, but still cool. will light up a room in pitch dark. Very bright. And it is focusable.

All I can say is this thing is a BEAST. For only $100, this thing will burn straight through electrical tape, plastic and cardboard (regardless of color). You can cut through electric tape in about 5 seconds. Close up, you instantly feel a burning sensation on your skin, and when focused, will melt your arm hair on contact as well as anything else you out in front of it. $100 may seem like a lot, but you won\'t find a 5W laser any cheaper than this. \n\nPURCHASE LASER GOGGLES WITH THIS. It is literally like looking at a welder without any eye protection, and if you don\'t use any, you WILL get eye damage, even without looking straight at the beam.

I have had more than a dozen lasers from this site alone, but nothing more than 500mW. I am sure this one is not 5W but it doesn\'t matter. This thing doesn\'t need to be anymore powerful. You can see the beam in daylight and start fires on the other side of the room. Batteries go fast because you are drawing a lot of power from them. Be careful with anything this strong. The reflection off a road sign at 1/4 mile is blinding. I strongly encourage you to get one of these at this incredible price. I should have got one long ago.

This site is awesome! They have great prices and products made with really good quality. I don\'t think it said it was focusable in the description but it is and is a great burning laser for the price. I would recommend this site to anyone!

I bought this 5,000 mw laser thinking that it was too cheap to be all that great. But I was wrong. This thing is awesome! I\\\'ve burnt just about everything that I own now. If you buy one, be sure to buy some laser glasses because they are crazy bright and it is like looking at a welder without them.

Absolutely love this thing. Does all of the burning examples and more. Courteous service and very fast shipping. The only thing that I don\'t understand is that this laser comes labeled as a class IIIB laser, I\'m pretty certain it\'s a class IV? I can\'t be sure.
