Laser classification table - Laser Safety Facts
网页For visible-beam consumer lasers, there are four main classes. Each is described in more detail here: Class 2, Class 3R, Class 3B and Class 4. The first two Classes are relatively safe for eye exposure; the last two are hazardous. The chart below shows how the eye injury hazard increases as the laser’s power increases.

Laser safety - Wikipedia
网页A Class 3R laser is considered safe if handled carefully, with restricted beam viewing. With a class 3R laser, the MPE can be exceeded, but with a low risk of injury. Visible continuous lasers in Class 3R are limited to 5 mW. For other wavelengths and …
Safety of Class 3R visible-beam lasers - Laser Safety Facts
网页A 4.99 mW Class 3R laser beam can temporarily flashblind a pilot or driver, causing afterimages, within 530 ft (160 m) of the laser. It can cause glare, blocking a pilot or driver's vision, within 2400 ft (730 m) of the laser. It can cause distraction, being brighter than surrounding lights, within 4.5 miles (7.3 km) of the laser.
Laser Safety: Class 1, 1C, 1M, 2, 2M, 3R, 3B, and 4
网页2018年9月14日 — Class 3B. These laser products are considered more hazardous and relatively unsafe under direct and specular reflection viewing conditions. A Class 3B laser product, however, is normally not a fire hazard, diffuse reflection hazard, or a laser generated air contaminant (LGAC) production hazard. Class 4. …
Laser Pointer Safety - Laser Classes (1, 1M, 2, 2M, 3R, 3B, 4)
网页There are four main classes for visible-beam lasers: Class 2, Class 3R, Class 3B and Class 4. The first two are relatively safe for eye exposure; the last two are hazardous. The chart below shows that the eye injury hazard increases as the laser’s power increases.
Understanding Laser Classes & Laser Safety | KEYENCE America
网页Class 3B lasers are lasers that use intermediate power from either 5-500mW CW or pulsed 10J/cm2. Operating a Class 3B laser incorrectly can result in eye damage or skin burns. Because of this, Class 3B lasers require laser safety goggles and laser safety warning labels. An example of Class 3B lasers is 3D printers.
Laser Classification Explanation - Lawrence Berkeley National …
网页2018年6月4日 — Class 3R (replacement for Class 3A) A Class 3R laser is a continuous wave laser, which may produce up to five times the emission limit for Class 1, or Class 2 lasers. Although the MPE can be exceeded, the risk of injury is low. The laser can produce no more than 5 mW in the visible region.
