Class 1, 1M, 2, 2M, 3R, 3B and 4 indicate the danger degree of the
laser radiation specified below according to IEC 60825-1:2001.
Class 1: Lasers that are safe under reasonably foreseeable conditions
of operation, including the use of optical instruments for
intrabeam viewing.
Class 1M: Lasers emitting in the wavelength range from 302.5 to 4000
nm that are safe under reasonably foreseeable conditions of
operation, but may be hazardous if the user employs optics
within the beam. Two conditions apply:
a) for diverging beams, if the user views the laser output with
certain optical instruments (for example, eye loupes,
magnifiers and microscopes) within a distance of 100 mm;
or
b) for collimated beams, if the user views the laser output
with certain optical instruments (for example, telescopes
and binoculars).
Class 2, 2M, 3R, 3B and 4 does not apply.
CAUTION
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
The use of optical instruments with this product will increase eye
hazard.
