LASERVISION Safety windows

Mineral glass and plastic laser safety windows

Mineral glass and plastic laser safety windows are one of the three key product ranges of the LASERVISION portfolio of laser safety products. Main applications for laser safety windows are the integration within machine housings or within large area laser protection, such as cabins or panel barriers. The basic standard for laser protection (DIN EN 60825-1:2008) demands that lasers need to be safely operated under all predictable conditions. That means, that the accessible laser radiation must be below the maximum permissible exposure for the eye and skin. According to the machine-building regulation 2006/42/EG laser protection windows and enclosures are considered as safety components.

Mineral glass laser safety windows have been the only solution for visual process observation within laser systems for many years. Due to the manufacturing process of mineral glass laser safety windows, it can only be built up to a maximum size of 297x210mm (DIN A4) to keep the needed optical quality. If larger window sizes are needed it is necessary to mount more windows side by side or they have to be mounted as lattice windows. In contrast to that, some plastic laser safety windows can by default be shipped up to a size of 2000 x 3000mm. Thereby the user has additional freedom of design of his machine or cabin. For special high laser power ratings or for unobserved and automatic workstations LASERVISION offers a patented active laser safety window which ensures, that in case of a laser hit, the laser will be shut down immediately. This active large area laser safety window is especially suitable for the industrial used laser wavelength 820 – 1100 nm.
