LASER LI G HT
Low-power lasers are by definition incapable of duration of the blink (aversion response) of 0.25 visible wavelengths (400 - 700 nm). Therefore, individuals overcome their natural aversion to a bright laser beam.

COMPLIES TO 21 CFR PART1040.10 AND EN60825-1:1994 • Do not permit a person to stare at the laser from within the beam.• Do not point the laser at a person’s eye at close range.• The beam emitted by a Class 2 laser product should be terminated at the end of its useful path. Open laser beam below eye level, where practical. More information online at
