An astronomyLaser Pointer Blue 30000mw looks much like its regular red cousin on the outside. It is shaped like a thick pen. The beam of an astronomy 20000mw laser pointer, however, is green and about 60 times brighter than the red version. The curious properties that makes these pointers extraordinary is that the beam creates the illusion to the human eye that it is stopping at the object toward which it is pointed. The beam can be followed from hand to sky to accurately point out objects as small as stars.

The standard for an astronomy laser pointer is 5 milliwatts (mW) of power and a laser wavelength of 532 nanometers (nm). Higher wattage pointers, up to 500 mW are available, but are not always safe to use. The technology used to emit a laser of this power and frequency is more complicated than the common red type. Because a direct diode would cost thousands of dollars, it is necessary to mechanically and electronically convert a laser beam of a frequency that can be cheaply produced. The extra technology makes the astronomyGreen Laser Pointer 3000mw

10000mW 532nm green laser pointer can often be found in office supply stores and electronics retailers. They can also be found by shopping on Internet. There, they will find the Laser Pointers category.In addition, the laser colors available on Internet include red, green, blue, purple, and yellow. Buyers who are in the market for ultra-powerful lasers can also find a variety of suitable safety glasses in the laser pointers category. As a result, Internet provides buyers with everything that they will need to safely use a wide range of laser pointers.
