Class 3b lasers are lasers that powered from 5 to 500 milliwatts and Class 4 lasers have output powers of more than 500 milliwatts. They set out a structure for defining classes of laser-based on power and wavelength. I will be using the laser to sinter/melt plastic in the context of 3d printing. %PDF-1.6 % Fortunately, wearing laser safety glasses or goggles can protect the eyes from the risks that lasers pose. Have your Certified Laser Safety Officer make certain you are using glasses and goggles with the correct wavelength and OD. When you work with this laser, laser protective eyewear is mandatory. Therefore, if you want to cover several wavelengths in the visible spectrum the Optical Density curves will overlap resulting in dark filters or glasses. I am glad I attended. The law requires a key switch and a safety interlock to come with all Class 4 lasers. The class never seemed like a class; it was just a positive learning experience. The classifications of lasers are based on 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). Everybody exposed to a Class 4 laser beam must wear appropriate safety glasses. Laser safety eyewear is available for different wavelength ranges and for specific types of lasers. startxref More information as well as instructions on how to disable individual analysis functions can be found in our Privacy Policy.
