Laser Pointer Keychain

The uses of 100mw green laser pointer pen

The 100mw green laser pointer pen can cut thin plastic. Most of the keychain green laser pointer does not have IR filter. This means that they can be hazardous to eyes without proper protective eye wear. What this means is that in case you are unsure of what this means get the 5mw version for your safety.

The 100mw green laser pointer pen is capable of burning holes on and cutting thin plastic films. Ensure that you have protective eye-wears and that you do not misuse the keychain green laser pointer.

In some countries the 100mw green laser pointer pen may be illegal to own or use. It has a maximum output of 100mw. The wave length is 532nm, and it is a class 3B laser. It is powered by 2 AAA batteries and takes 0 to 60 seconds to reach full laser strength.

The keychain green laser pointer is about 2 times brighter than the 10mw green laser. It has a bigger dot and a more visible beam.

The astronomy laser pointer functions as a wonderful Finder with unique advantages. It is a new variation of an old idea. Amateur astronomers have been practicing it for many years. The astronomy laser pointer is a narrow-beam high power flashlight that has been used to point out celestial objects. Tiny particles of dust, pollen, as well as moisture are able to scatter back enough light from the beam in order to produce a visible line in the air. In case the beam extends far enough, any designated location on the sky can be pointed out with the astronomy laser pointer.

Nowadays there is increased interest in science and astronomy education, leading to a growth of astronomy clubs and star parties. The astronomy laser pointer provides a convenient and practical way to show as well as teach celestial geography.

Though red laser pointer is cheap and ubiquitous, but it is not as effective as an astronomy laser pointer. The keychain green laser pointer is very effective due to the greater sensitivity of the eye to the 532 nanometer green light. Under dark sky conditions, the beam from a keychain green laser pointer creates a dramatic impression, and the beam can apparently extend for more than a kilometer. Any bright light source, such as light pollution induced sky glow to a crescent moon, tends to reduce the apparent brightness of the keychain laser pointer although the beam usually remains visible.
