Gone are the days when green laser pointers used to be very expensive. Now, it is not only easily available but is also within the reach of an average consumer’s pocket. You can find it everywhere, including electronic stores, hobby shops, and probably in that corner drugstore near your home. However, there are several things that are very important for you to take into your careful consideration when it comes to comparing the different models and choosing the best out of them. Always remember, though the basics are almost the same, they might be different in terms of their construction and how they can be used. If you do not know what factors you have to look out for, it will not at all be an easy task for you to compare the different models of laser pointers. Following is a brief rundown on how to choose the one that is the most suitable for your specific needs.

Type Of Battery

The first thing you have to do is look into the type of battery they are using. After all, if the power supply is not proper, it will affect its performance. Button batteries are often considered as a better choice as compared to the AA batteries. But, you must keep in mind that button batteries are not readily available. AA batteries on the other hand are not only easily available everywhere but they are also less expensive.

The Option To Turn The Laser On And Off

When it comes to comparing different laser pointers, it is important for you to make sure that it provides you good control over switching the laser on and off. There are generally two options available in this regard. Where some products use a sliding switch, others use a push button. The push button seems to give you more control, but it is up to you to decide which type of option you are comfortable with.

Type Of Lens

There are two types of lenses that are generally used in these products to focus the laser – plastic lens and glass lens. You should prefer to go for the one with glass lens because it strengthens the output of the beam. On the other hand, plastic lenses are very much likely to go cloudy over a period of time, which will obviously adversely affect the performance of the laser pointers.

Infrared Filter

While you are using a laser pointer, you must have some mechanism to eliminate the dangerous IR radiation. So, make sure that the product you are considering buying has an infrared filter for this purpose.

Warranty

Last, but not the least, do not forget to check the warranty period that comes with these products. Obviously, you should go for the one that offers you a much longer warranty.

Remember, the beam of laser can be very dangerous if you aim it at someone’s face because you may end up damaging his/her eyes. So, you have to be very careful about how you are going to use these green laser pointers.
