Ageing resistance of laser protection filters

Project number: F 2442 Institution: Federal Institute for Occupational Safety and Health (BAuA) / Bayerisches Laserzentrum GmbH Status: Ongoing Project Planned end: 2019-10-31


The intended protection of laser protection filters and laser protection goggles are important components in the application of personal protective measures for the safe operation of higher power lasers. In the course of time, the protective effect can be reduced or even reduced to ineffectiveness by use or by material-related processes within the filter materials.

The reduction of the protective function of an aged or used protective goggles with scratches, opacities, fading, etc., has not been quantified so far. Even for laser protection specialists, no criteria are available for easily assessing the protection of an aged protective goggle. Based on these considerations, this project aims to provide practical help for laser protection specialists, safety specialists as well as company users.
