Green Laser Pointers Make Highly Useful Signaling Tools

A new laser pointer is a small device that emits a narrow, low-powered laser beam of light. Typically, a laser pointer is used to highlight an item of interest by illuminating that item with a tiny, brightly-colored point of light. The narrow width of the light beam and low power of laser pointers makes the light beam invisible until it strikes an opaque surface.

What features come with a green laser pointer?

You will find a variety of features available on green lasers for sale on eBay. This can help you determine which laser pointer is right for you as well as determine the price point. These include:

  • Adjustable focus and zoom
  • Battery and charger
  • Cigarette lighter
  • Pattern adapters
  • Presentation controls
What power levels are available with green laser pointers?

A higher-frequency and higher-power green laser pointer may produce a visible light beam. In addition, green laser pointers are preferred for pointing out astronomical objects. Green lasers for sale on eBay are available in three primary power levels:

  • 1 mW
  • 5 mW
  • 10 mW
  • 100 mW
What should you take into consideration when buying a new or preowned green laser pointer?

Consider the reasons why you are buying an inexpensive green laser pointer when making your choice:

  • Burning power - If you plan to use your affordable green laser pointer to start a fire, you'll want to make sure that it has at least 200mW output power.
  • Visibility - Our eyes are better adapted to tracking green laser light than they are other colors. If visibility is important, opting for a green laser over other colors, such as red, is a good idea.
  • Safety -- Laser pointers can be fun and useful, but there are also risks involved with using one. An adjustable focus is one such feature; another is a lens cap. If safety is a significant consideration, check the description of the green laser pointer that you are considering so that you can choose one that provides the level of safety that you desire.
