CDRH Classification
The Center for Devices and Radiological Health (CDRH), a part of the U.S. Food and Drug Administration (FDA), has a laser safety classification scheme.

![]() |
![]() | ||
Your choices are... | |||
Class I | Class I lasers are not hazardous for continuous viewing, or are designed to prevent human access to laser radiation. Class I lasers include both low-power lasers and embedded, high-powered lasers. Applications include laser printers. | ||
Class II | Class II lasers emit visible light which, because of the normal human aversion response, does not normally present a hazard. If viewed directly for extended periods of time, however, Class II lasers can cause eye injuries. | ||
Class IIa | Class IIa lasers emit visible light that is not intended for viewing, and that under normal operating conditions will not injure the eye if viewed for less than 1000 seconds. Barcode scanners use Class IIa lasers. | ||
Class IIIa | Class IIIa lasers will not normally injure the eye if viewed momentarily, but present a hazard if viewed using collecting optics. | ||
Class IIIb | Class IIIb lasers present an eye and skin hazard if viewed directly. This includes both intrabeam viewing and specular reflections. Class IIIb lasers do not produce a hazardous diffuse reflection except when viewed at close proximity. | ||
Class IV | Class IV lasers present an eye hazard from direct, specular and diffuse reflections. In addition, they may pose a fire hazard and burn skin. | ||
Other | Other unlisted CDRH classifications. | ||
