Always consult your on-site Laser Safety Officer (LSO) for specific guidance. Required optical density (OD) and laser safety personal protective equipment (PPE) are determined based on worst-case scenarios and require professional judgment. All laser safety equipment provided is intended for diffused beam viewing only.
Our laser safety windows 405, 406, and 407 are all suitable options for protecting against a 355nm laser with a power rating of 3W. The 406 and 407 models are particularly popular because their color provides a more opaque appearance, enhancing the perception of a secure barrier.
