What are lasers used for?
Standard laser pointers are commonly used for a wide range of applications. Anything from military training, astronomy star gazing, giving a presentation to a large number of people, or plain old hobbyist use. They are convenient in size and require basically no maintenance or upkeep minus battery usage.
What laser color is the brightest?
532nm green is always the brightest laser beam color at the same output power. Meaning that 100mW of green will be 7x – 10x brighter than 100mW of any other color, making it the most commonly used for astronomy, military, and hobby use alike.
What are the safety concerns with lasers if any?
The only real safety concern users must take into account when engaging a laser beam is to be wary of reflective surfaces which can repel light into the eyes of spectators of the user themselves. Also, never take aim of any aircraft or vehicle as this is highly dangerous and highly illegal.
If you’re looking to buy a laser pointer online it will be important to conduct your own research as to what will be the most suitable model specifications for your needs. How much power and what color are you looking for? What is the warranty period and expected lifetime of the unit? All questions to be answered before you buy.
