Laser Light can damage the human eyes and skin. Do not expose the eye or skin
to laser light directly. This Laser product has an optical lens and emits a
collimated laser beam. The light from this product, both direct and reflected, is
very harmful as it can propagate a long distance while maintaining high optical
density. When handling the product, wear appropriate safety glasses (OD5+) to
protect eyes from laser light including reflected and stray light. The reflected and
stray light spilling into an unintended area should be attenuated and/or absorbed.
