WHAT IS A CLASS iv High power LASER?Class 3B lasers are hazardous for eye exposure. They can heat skin and materials but are not considered a burn hazard. For visible-light lasers, Class 3B lasers'' output power is between 5 and 499 milliwatts. Class 3B is the same as the Roman numeral "Class IIIb" you may see on some lasers'' labels. At this website, we primarily use the Arabic numerals, for convenience.SAFE USE GUIDANCE - GENERALClass 3B visible-beam lasers are medium powered, from 5 to 499 milliwatts. A Class 3B laser can cause eye injury. The more powerful the laser, the greater the chance of injury. Use of laser protective eyewear is suggested or recommended (depending on the laser''s power level), as discussed elsewhere on this page. A Class 3B laser can be a distraction, glare or flashblindness hazard for pilots and drivers. NEVER aim any laser towards an aircraft or vehicle that is in motion. This is unsafe and is illegal -- you could be arrested and jailed. Always be aware of the beam location. Keep it away from people''s eyes and heads. Watch out for reflected beams from glass and shiny surfaces. When outdoors, you must avoid aiming at or near aircraft.ONLY ALLOW USE BY RESPONSIBLE PERSONS This is not a toy. Children should not be permitted to use Class 3B lasers. Any teenager using a Class 3B laser should be continuously supervised by a responsible adult. A number of teenagers have caused eye injuries to themselves or others by misusing Class 3B and Class 4 lasers.DO NOT USE AS A LASER POINTER Class 3B (and 4) lasers are too powerful to be used as pointers. Some Class 3B (and 4) lasers may look like pointers, but these should not be used for pointing. Use a Class 2 (less than 1 mW) or Class 3R (less than 5 mW) laser for pointing purposes.CLASS 3B LASER HAZARDSSAFETY NOTICE: This website is intended for the educational, instructional and informational purposes of the user and is not to be considered a substitute for a knowledgeable and trained Laser Safety Officer (LSO) with the duties and responsibilities as defined in the ANSI Z136 standard published by the American National Standard Institute. The hazard distances listed below are intended only as general guidance. This is because 1) your laser may vary from the parameters (power, divergence) listed below, and 2) information on labels or marketing materials may not always be correct. For example, studies have shown that some laser pointers may be falsely labeled to avoid regulations -- the actual power may be 10 times or more what the label indicates. Always err on the side of safety. If your laser has not been measured by a knowledgeable and trained Laser Safety Officer, assume it is more hazardous than the label or marketing materials would indicate.EYE INJURY HAZARDSEYE INJURY HAZARD -- DIRECT AND REFLECTED BEAM Class 3B visible-light lasers are hazardous for eye exposure. They can cause burns to the retina. A person cannot turn away or blink fast enough to prevent retinal eye injury from a nearby Class 3B laser. At the low end, around 5 to 50 milliwatts, a Class 3B laser poses a moderate risk of eye injury. It is unlikely that a handheld beam aimed from more than a few dozen feet away would cause injury -- laser light could not stay on one spot on the retina long enough for heat to build up to injurious levels. However, the risk is increased if the beam is held steady or if the laser is relatively close to the eye. As the laser power increases, the risk of eye injury also increases. At the high end, around 250 to 500 milliwatts, even a brief exposure could cause retinal damage.
