A big question facing anyone in the market to buy lasers has always been the difference between colors and output powers of the wide variety of laser pointers available. What color is the brightest? How far can a laser be seen? How much power do I need for burning lasers? All questions posed by enthusiasts on the hunt for the most suitable model for their needs.
Beam Color Frequency – Nanometers
Lasers produce condensed beams of light, therefore, the colors are measured within the visible light spectrum using the nanometer (nM) scale. 532nm green is the brightest color to the human eye, this means that green laser pointers at the same output power as any other color will be 7x – 10x brighter. Because of this fact green lasers are now the most popular and typically desired color simply because of how vibrant they appear.
Power and Distance
If you’re looking to have a laser pointer with burning ability you’ll need a minimum of 100mW of power and naturally the more the better. Any color is suitable to burn when at the right output power, but distance of visibility will be different. Just as green lasers are 7x – 10x brighter, they are also visible from much further distances than any other color.
With even just a little bit of research you can find a high quality green laser pointer that does not disappoint. There is a wide variety of places to buy lasers online, just ensure you’ve done your research into any brand and laser company that you’re considering going with.
