Protective glasses against laser radiation

Like glasses and goggles, laser radiation protection glasses mounted on enclosures, doors and partitions used to isolate the laser radiation source from the external environment are built on the basis of special filters with varying degrees of protection and visible light transmission. Unlike goggles, they are designed to protect not only the operator, but also third parties in the immediate vicinity of the device or room where laser processing tasks are carried out. The selection of a suitable protective rapid filter depends on the operating parameters of the laser: wavelength range, power and mode of operation (cw, pulsed, high-power pulsed, modal). The material of the filter also plays an important role, although today they are mostly made of plastic. To be sure of the right choice of the type of filter, and thus the degree of protection of the glass, it is also necessary to take into account its purpose, i.e. the place of installation and the risk of exposure to radiation at that particular point in space.
