Lasers range in price which is effected by power, beam specifications, scanner speeds, unique feature sets, construction and weather proofing.
Many lasers series are available in different configurations that affect the number of visible colors available. 1-color and full color (thousands of colors) are the most common while some series are available in 2-color, 3-color or 7-color.
You new laser can be used for overhead beam shows and/or projecting graphics and text.
Beam divergence is the angle of which the laser beam slowly grows in diameter over distance. In general longer distances require lower divergance ratings and higher precision optics.
When speaking about the laser beam's visibility, a few key factors must be considered. When projecting laser beams the goal is to have a high contrast in brightness between your beams and your background or "ambient" lighting. Otherwise the laser beams will blend in with the ambient lighting conditions. In general lower ambient lighting requires less power.
The second factor that determines power requirement is the use of fog or haze machines. The use of fog or haze greatly increases visibility and thus reduced the power requirement. Without any fog, haze or smoke of any kind you need considerably more power to achieve visible mid-air beams.
Enclosed spaces keep in fog and haze while keeping out exterior street and moonlight. Although outdoor spaces can achieve similar results at the same power, wind blowing away your fog combined with moonlight typically raises the requirement to guarantee a visible laser show.
Weatherizing can ensure your laser components are protected in a variety of outdoor conditions. You may also consider weatherizing when indoor conditions are suseptable to high fluctuations in temperature. Lasers always operate best at a warm dry climate.
Beam divergence is the angle of which the laser beam slowly grows in diameter over distance. In general you want your graphics beams to be sharp and crisp which requires lower divergence the farther the wall or screen is from your laser projector.
Darker walls will require higher power than lighter color walls.
All lasers shipped within the U.S. require safety features verified by the FDA. This is known as a "variance" and all lasers shipped within the US must have one by law.
