Laser Safety Eyewear - Alignment Filters

R-rated filters for the safe viewing of visible laser beam spots

LASERVISION's alignment filters provide partial blocking of low power, visible wavelength laser beams. This means that the wearer can safely view the visible beam spot for laser beam alignment. Alignment filters are assigned an R rating in accordance with BS EN 208. The principle of alignment protection filters is that they attenuate the power of the laser such that if the beam were to accidentially hit the filter directly, the only light that would be transmitted would be equivalent to a class 2 exposure. Class 2 lasers are those low power, visible devices for which the eye's blink reflex affords sufficient protection. Please note that alignment filters are not intended for direct viewing of the laser beam, rather for diffuse, indirect viewing (i.e. reflections from a scattering surface).
