1 week ago This type of laser is the most hazardous. Class 4 lasers care unsafe when a direct beam is exposed to the eye or skin. Furthermore, this laser can pose a fire hazard or diffuse reflection hazard, and it can also produce LGAC and even hazardous plasma radiation. Please note that the laser classes apply to almost all laser products and/or systems, wh...

4 days ago Lasers have been classified by wavelength and power into four classes and a few subclasses since the early 1970s. The classifications categorize lasers according to their ability to produce damage in exposed people, from class 1 (no hazard during normal use) to class 4 (severe hazard for eyes and skin). There are two classification systems, the "old system" used before 2002, and the "re…
