These precision manufactured lenses have been designed to allow users to increase laser brightness on effects used to scan audiences, without increasing potentially harmful exposure levels. They are designed to be mounted at the laser projector’s scanner output, acting on effects that travel below the horizon, softening power density of these beams, but increasing the beam divergence by a set amount, providing a very effective means of keeping effects below the exposure safety limits (MPE).

 

Six different strengths of lens are available allowing the divergence of the beams used in the audience scanning effects to be adjusted as required by the environment they are being used; short projection distances such as nightclubs etc, will likely require one of the stronger lenses (-4 to –6) to increase the divergence on the lower audience scanning beams. While use in larger venues, scanning over greater distances can often use one of the lesser strength lenses (-1 to -3).
