Laser safety glasses and goggles are used to protect eyes from indirect viewing and unintentional direct viewing of lasers - you should never intentionally look directly at or at the reflection of a laser beam as demonstrated below. While providing protection from the laser, the glasses and goggles allow other light or visible light transmission ("VLT") to come through enabling the viewer to see the field in front of them. Below, we have included an image displaying the different types of viewing of a laser - the first two images displaying viewing that should never be done - direct viewing of a laser. or its reflection.
Different goggles protect from different types of laser. Most of the time the lasers come with the safety requirements and needed optical density at the particular wavelenegth(s) that need to be followed. We've demonstrated with an image an eye safe aiming beam coupled with an operating beam that requires laser safety protection. Never look at any laser directly— including the aiming beam (stand behind the beam while viewing it). Do not bring your eyes near the axis during alignment or any other operation with lasers. All laser safety PPE is for unintentional direct and diffused viewing only. Proper laser safety is to NEVER look directly at a laser beam. If you are in doubt whether or not your aiming beam is eye-safe for diffused viewing, check with your Laser Safety Officer or call us before making any assumptions.
