Is it possible to exclude a direct laser hit of the window or a direct reflection of the laser beam caused for example by a tilted workpiece so the installation of plastic laser safety windows in laser protection housings is also possible, if the optical density is high enough. Plastic windows have the advantage compared to mineral glas windows to be available in significantly larger dimensions. For many applications the largest size for plastic sheets is 610x915mm² or meanwhile 915x1220mm², while mineral glass windows certified with L protection levels are available depending on the wavelength only up to DIN A4 or 100x200mm².
At all popular YAG wavelengths LASERVISION’s P2000 shows a optical density of 5+ and at the classical Nd:YAG pump diode wavelength 808nm the OD is 3+. The visble light transmission is appr. 26%.
