With so many different laser pointer varieties and options to choose from today, knowing which model suits you best will depend on a number of different factors. Here we’ll look at some of the basic design features and what they mean for each user and each laser unit individually.
This is pretty straight forward as certain lasers (be them high, medium, or low power) incorporate safety features like a keyswitch which will not allow the laser to be engaged without the proper key usage. This is a great safety feature for anyone with small children around as they cannot simply pick up the laser and start shining it.
2. Focus Adjustable
This is a very popular feature for both high power burning lasers as well as lower power units. Having the ability to focus or widen a beam can allow you to pinpoint targets at distance more effectively, whether for search and rescue, construction, star gazing, military applications and more, many users prefer the focus adjustment options as it offers you more control over the lasers output and brightness.
3. Rechargeable Batteries
Classic pen style laser pointers almost always uses AA or AAA batteries, and though there is nothing wrong with that at all, higher power lasers can have a tendency to use a fair bit of energy. For this reason, most stronger lasers these days utilize rechargeable lithium ion batteries to keep lasers going and no need to buy or replace batteries. It’s still a good idea to have a few extra rechargeable batteries around so that you can be using a set while your other set is charging and never have any down time when you need a beam of laser light.
This was a brief look at the most common and functional laser designs out there today. Be sure to do your own research and make your own determination of the style of laser, color, output power, and design features that suit you best. Keep in mind that Green Laser Pointers are always the brightest at the same power, meaning a 100mW green laser is 7X brighter than a 100mW of any other color.
