Since the boom in laser pointer popularity in the 1990s, there have been countless makes and models of laser pointers put on the market. Each different laser pointer has its own features that are suitable for different situations and needs, including the power of the laser, the size of the pointer, and of course the cost of the pointer.
Red Laser Pointer:
Red laser pointers are by far the most popular and least expensive type of laser pointer. This is because the wavelength of the red color can be manufactured more easily than that of the other colors in the spectrum. Red laser pointers are also the only color that is available in the smallest size of laser pointers.
Green Laser Pointer:
Increasingly, green laser pointers have become more popular, though they are generally more expensive than their red-colored counterparts, with many models costing upwards of $100 in 2012. Green lasers are simply more powerful than red lasers. They are much brighter and can be seen from much greater distances, even while operating under 5mW. Of course, this also means that green lasers are potentially more dangerous than red lasers. When operating this type of laser, it is important not to point it into anyone’s eyes or to point it up in the sky towards any airplanes, which is actually a federal offense in the United States.
Laser pointers can be a useful tool for professional presentations or a fun toy for entertaining the family pet. Of course, not all laser pointers are suitable as toys. It’s important that individuals carefully evaluate their needs and choose a laser pointer that will be safe and appropriate for its intended application. For those who need a laser to perform substantial work, there are also many powerful laser pointers that, when operated properly, can be truly spectacular. Depending on any individual’s needs and budget, there is a laser out there that will fit perfectly.
