How to choose laser pointer?

Posted on by

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.

Anyone will be puzzled while various kinds of laser pointers are available from different laser suppliers. It’s 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.

You should pay much attention to following points while choosing laser pointers:

Color

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.

Power

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.

On/off Switch

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.

Presentations

Charming and bright visible beam have made the blue and green lasers become the quite proper choices for presentation.  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.

Astronomy

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.

Burning

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.

Safety features

Lens shutters, elaborate range of keys, dongles, and time delay would all of the possible safety features.

I have got different kinds of laser pointers from these three website, and the followings are my opinions of their laser pointers for your reference. Anyway, I would say that a laser pointer which has really met your need is just the right laser worth to buy.
