Much brighter than the standard red variety, these green lasers are perfect for applications where the beam must be observed, such as when demonstrating lenses, prisms or mirrors, or in long distance applications. The bright green beam is especially effective when observed in water. Simply direct the beam through the flat glass side of an aquarium filled with water. Add a few milliliters of milk to clearly observe the beam. Great for large group demonstrations. As this is a true laser, please exercise care when using this fantastic and educational device. Class IIIA <5mw 532nm. Uses 2 AAA batteries, included.About Continuous Beam Lasers:
Many green lasers blink on and off rapidly, often faster than the eye can perceive. This can impact the results of some experiments. Continuous beam lasers do not blink, resulting in a higher perceived brightness and requiring less reflective particles (dust or mist) to see the beam in the air. (All lasers require some reflective particles to be visible in air.)
