Red 200 MW Laser Dangerous?
this is very dangerous. A stray reflection from a reflective spot can hit someone’s eye and cause permanent damage. Even through a window. When these are used, they are used only in a room with no windows and controls so that everyone wears the proper protective goggles. see the reference, I think this is a class 3B or 4 Class 3B LASER RADIATION AVOID EXPOSURE TO THE BEAM CLASS 3B LASER PRODUCT A Class 3B laser is hazardous if the eye is exposed directly, but diffuse reflections such as from paper or other matte surfaces are not harmful. A diffuse reflection is generally not hazardous but specular reflections can be just as dangerous as direct exposures. Continuous lasers in the wavelength range from 315 nm to far infrared are limited to 0.5 W. For pulsed lasers between 400 and 700 nm, the limit is 30 mJ. Other limits apply to other wavelengths and to ultrashort pulsed lasers. Protective eyewear is typically required where direct viewing of a class 3B laser beam may occur. Class-3B las
