not stare into the beam or view directly with optical instruments. Viewing the laser output with
certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance
of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other
than those specified may result in hazardous radiation exposure.
