Blue Laser pointers with 405 nanometers wavelength of light. 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 lasers than red lasers 6 times more than red laser 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 lasers was released in the early 1980s. Nowadays, the More durable 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 lasers are powerful since the light they emit is powerful when it hits a certain object and converges into a point.
Now, more and more laser pointers and Laser flashlight 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 powerful laser pointer, wear special secure glasses would be safe, especially for the invisible laser.

Had a green standard 200MW laser with no focus paid more than the asking price of this focus 230mw laser. Sucks it does not have a charger and rechargeable battery however I bought a charger for 5$ and 2 4000Mah lithium rechargeable batteries for 5 bucks overall spend 48$ and some change to be happy will update my review once it arrives further about the product.
Finally got it after waiting 3-4 weeks. Happy with the laser though. For the money it has a nice beam that is quite strong. At night or in a dark room the beam is very visible. I can splash it on things that I know are several miles away. For $30ish dollars I am quite happy. Kind of lame that is doesnt come with a simple charger.
I have purchased several "Green" lasers over the past few months, Dollar for value, this one has been the best purchase yet. !!! Yes,I have popped balloons from as far as 8 feet away!!! The beam at night is unbelievable. This was my first purchase "Laserpointerpro" Quick shipment !!!! Great little laser. Well worth the money.Thanks for providing quality lasers at affordable prices, David (Tennessee)
