Astronomy Laser Pointer - Buying an Astronomy Laser Pointer - Top Models of Astronomy Laser Pointer

quality beam pointers red

We are all aware of the red laser pointers like those used by class clowns to incite a laugh or by kids at a movie theater to point out peoples’ unmentionables. There seems to be no legitimate practical use for them. What most people are not aware is that there is a different type of laser pointer available to consumers that can be used outside at night to point out distance objects and astronomical features such as stars thousands of light years away.

An astronomy laser pointer looks much like its regular red cousin on the outside. It is shaped like a thick pen. The beam of an astronomy 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 astronomy laser pointer more expensive than the red pointer.
