As a laser pointer lover, I know it is a hard job to choose the right laser pointer while the first experiencing various laser pointers from a large quantity of different supplier.<\/p>\n
Anyone will be puzzled while various kinds of laser pointers are available from different laser suppliers. It\u2019s really a hard work to decide which laser pointer to buy. As a laser pointer enthusiast I have got some experience on choosing the right laser pointer. Here is some of my experience of choosing a laser pointer, and I hope it can help.<\/p>\n
You should pay much attention to following points while choosing laser pointers:<\/p>\n
Color<\/p>\n
Lasers are available in red (632nm), green (532nm), blue (473nm), yellow (594nm), and DPSS (808nm to 1064nm), which determines the brightness, visibility and price of a laser. While the charming beam of rare laser has also become a new fashion among laser lovers as well as the most popular green laser pointer.<\/p>\n
Power<\/p>\n
The power, measured by mW (the abbreviation of Millwatts), available from 1mW until 700mW, which has decided the abstract application and the price of a laser pointer. However, danger will be also included with the improving of power.<\/p>\n
On\/off Switch<\/p>\n
Momentary off\/on push button and standard click off\/on switch are two typical types of switch. Hand free or not hand free will depend on the concrete application of laser pointer.<\/p>\n
Presentations<\/p>\n
Charming and bright visible beam have made the blue and green lasers become the quite proper choices for presentation.\u00a0 A low power laser has been enough for presentation, since a high power one with more than 5-10Mw would be a danger to yourself and people around you.<\/p>\n
Astronomy<\/p>\n
Green laser pointer is the unique choice for astronomy because of its long distance beam visibility. Power depends on the number of people around. Usually a laser pointer with a power range from 15mW to 35Mw is enough to watch celestial objects. A hand free laser is the best choice while mounting on a telescope and a hand control laser is an ideal choice while pointing.<\/p>\n
Burning<\/p>\n
Usually laser pointer among 100Mw-125Mw has been enough for burning matches and paper, popping balloons, and cutting electrical tape. However, the most exciting burning of cigarette, clothing and plastic would be never a dream with a 150-200mW green laser pointer if money permitted.<\/p>\n
Safety features<\/p>\n
Lens shutters, elaborate range of keys, dongles, and time delay would all of the possible safety features.<\/p>\n
