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 Hazard Classification - The Laser Institute
网页Class 3. A Class 3 laser or laser system can emit any wavelength, but it cannot produce a diffuse (not mirror-like) reflection hazard unless focused or viewed for extended periods at close range. It is also not considered a fire hazard or serious skin hazard.
Laser safety - Wikipedia
网页Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.
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.

网页2022年4月8日 · 激光切割. 激光安全等级Laser Safety Classes出于安全考虑，激光器可能对人的眼睛和皮肤造成伤害。 法律要求大多数激光产品必须有一个标签分类。 它将以阿拉伯数字 (1，2，3R，3B，4)或罗马数字 (I，II，IIIa，IIIb，IV)列出。
Laser Pointer Safety - Laser Classes (1, 1M, 2, 2M, 3R, 3B, 4)
网页Lasers are classified based on their potential for causing injury — especially eye damage, since the eye is most susceptible to excess laser light. 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.

Laser Safety: Class 1, 1C, 1M, 2, 2M, 3R, 3B, and 4
网页2018年9月14日 · The laser classes for safety are as follows: Class 1. Laser systems considered Class 1 are understood to be incapable of producing damaging radiation levels. Therefore, they are safe and are exempt from beam-hazard control measures. Class 1C. These laser products are designed explicitly for contact application to the skin or …
Section 3: Laser Hazard Classification | Office of Environmental …
网页The ANSI standard laser hazard classifications are used to signify the level of hazard inherent in a laser system and the extent of safety controls required. These range from Class 1 lasers (which are inherently safe for direct beam viewing under most conditions) to Class 4 lasers (which require the most strict controls). The laser ...

网页Laser/Laser System Classification, Maximum Permissible Exposures and Laser Bioeffects. There are seven levels of laser classification that include Class 1, Class 1M, Class 2, Class 2M, Class 3R, Class 3B, and Class 4. The details for classification are given in Section 3 and the associated tables in Z136.1-2014 (Ref 1).
