Wuben XP-G2 R5 260 Lumens USB Mini LED Flashlight

Green light is the most visible color to the human eye. This makes the beam from our laser pointers very bright with a spectacular vivid green color. Shoddy green laser pointer on the other hand do not just give out green light, they also give out infrared light. They're far brighter than red lasers, typically operating at 532nm in the Class IIIA range. Under 5mW, these lasers can be visible for thousands of feet in optimal conditions, which makes them completely viable for shining into the starry sky and more than capable of handling classroom pointing duties.

Blue beam light is a laser with a shorter wavelength, on the order of 360 to 480 nm of electromagnetic radiation. The shorter wavelength makes it appear blue to the human eye. Blue lasers have a shorter wavelength than the most commonly used red lasers. They can be produced using gases, indium gallium, infrared or diode lasers, all of which operate in the blue wavelength. Blue lasers have a higher storage capacity, and are used in a wide range of applications in telecommunications, computer storage and printing technology. A high power blue laser pointer can burn things because the beam is extremely concentrated light and light energy can be absorbed by some objects and converted to heat.

The difference between a red laser and a green laser light is that the red beam light has a longer wavelength (about 650 nanometers) than does the green (about 532 nanometers). Diode-pumped solid-state (DPSS) red laser pointers emitting at 671 nm became available. Although this wavelength can be obtained directly with an inexpensive laser diode, higher beam quality and narrower spectral bandwidth are achieved through DPSS versions. Cool red laser is provided on htpow at high quality and low price. On this page, you can find a wide selection of red lasers. If you need a laser pen, please click here and buy one.
