Laser classification table - Laser Safety Facts
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: Class 1, 1C, 1M, 2, 2M, 3R, 3B, and 4
2018年9月14日 · 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 non-ocular tissue.
Laser safety - Wikipedia
A Class 1 laser is safe under all conditions of normal use. This means the maximum permissible exposure (MPE) cannot be exceeded when viewing a laser with the naked eye or with the aid of typical magnifying optics (e.g. telescope or microscope). To verify compliance, the standard specifies the aperture and distance corresponding to the naked ...
Laser Hazards - Occupational Safety and Health Administration
Discusses laser safety in healthcare facilities and provides information on laser classification, laser hazards, and emphasizes the need for medical laser programs. Laser Effects on the Human Eye. OSHA and Laser Institute of America (LIA) Alliance, (November 2009). Focuses on the effect lasers have on the human eye. Laser Safety Checklist. OSHA ...
Class 1 Laser Products: Regulations Explained | Laserax
2021年8月25日 · Class 1 lasers are low-power lasers that are inherently safe. Class 1 laser products contain more powerful, higher class lasers that need to be enclosed to make them safe. For example, you could view the beam from a class 1 laser without any protective eyewear because the maximum permissible exposure (MPE) cannot be exceeded. However, exposing ...
ultraviolet lasers cannot be Class 2 (or 2M). We are unaware of any Class 2M laser devices intended for consumer use. If you do have such a laser, consult a qualified Laser Safety Officer for more detailed analysis. Class 3R is either: (1) From 1 to 4.99 mW into a 7mm aperture (e.g., pupil of the eye) or (2) five times the Class 2 limit of 2. ...
Laser Classification Explanation - Lawrence Berkeley National …
2018年6月4日 · Class 1 Product. This is a laser product or device which may include lasers of a higher class whose beams are confined within a suitable enclosure so that access to laser radiation is physically prevented. Such products do not require a laser warning label on the exterior, think of a laser printer. Class 1M
Laser Hazard Classification | Laser Institute of America
Class 1. A Class 1 laser is considered safe based upon current medical knowledge. This class includes all lasers or laser systems which cannot emit levels of optical radiation above the exposure limits for the eye under any exposure conditions inherent in …
Laser Standards and Classifications - RLI
Class 1 lasers are very low risk and "safe under reasonably foreseeable use", including the use of optical instruments for intrabeam viewing. Class 1M lasers have wavelengths between 302.5 nm and 4000 nm, and are safe except when used with optical aids (e.g. binoculars).
Laser Classification | Medical Health Physics - Cornell University
CD-ROM readers and laser printers are class 1 lasers. This class includes high-power lasers within an enclosure that prevents exposure to radiation, and that cannot be opened without shutting down the laser.
