Protective windows for blue and violet lasers are an essential safety feature for users of diode laser systems, which are widely used in compact engraving machines and CNC equipment. These sources most commonly emit radiation at wavelengths of 405 nm or 450 nm.
Despite the small size of these devices, their optical power typically falls within the range corresponding to hazard class 4. It is therefore important to use certified protective windows for blue laser diodes, which reliably protect the eyes from both direct and reflected beams. In this category, you will find laser safety windows for wavelengths of 405–450 nm, which fully comply with the European standard EN 207 and have verifiable protection levels (LB).
