Laser Pointers

Premium Laser Pointers for Sale on eBay

Laser pointers are a great tool for such tasks as conducting business presentations, lectures, speaking engagements, and stargazing. Instead of fiddling around with your mouse, it’s often easier to deliver presentations using a laser pointer so your audience can watch and reflect upon your expressions. On eBay, you can find a variety of laser pointers of different wavelengths, colors, and power.

While searching for an eBay laser pointer, you will notice that laser pointers are equipped with different color laser beams. The color of the beam is important because each color beam is usually associated with a different wavelength. Accordingly, inexpensive laser pointers with a red beam sell for a minimum price because they generally produce a wavelength of 650 nm, which is least discernible to the human eye.

In contrast, the green laser beam is more sensitive to the human eye offering a wavelength of nearly 532 nm. Nowadays, blue laser beams with a wavelength of 473 nm are also available for consumers. In 2010, multiple manufacturers introduced violet laser pointers that can generate a wavelength of 405 nm.

Finding suitable lasers for sale can be challenging, particularly if you are using the laser pointer for a specific purpose. Here are few important tips to keep in mind when looking for a laser pointer on eBay:

• You will require a powerful laser pinter for outdoor use that has green or violet beam. In contrast, orange, red, and blue pointers are primarily used indoors.
• Try to buy a pointer that uses standard batteries such as Double-A or Triple-A. A rare laser pointer with special batteries may limit your use as they are often hard to find.
• A pointer with a red beam is the most inexpensive lazer pointer in the market. If you're buying a laser pointer with a red beam, make sure it is practical for the use; otherwise, spend a couple of dollars more to get a pointer with a higher wavelength.

For outdoors, if you’re planning to buy a strong laser pointer from eBay, then opt for a pointer that is at least 5mW for outdoor use. Also, make sure that the pointer has violet or a blue beam as these will be easily discernible in the standard daylight. For use in broad daylight under the sun, you will need a laser pointer that has an output greater than 5mW.
