This document applies to protectors intended to provide protection against accidental exposure to laser radiation within the wavelength range 180 nm to 1 mm. It defines the requirements, test methods and marking. Protectors intended for adjustment work on lasers are included in the scope of this document, and are marked in the same way as other protectors, but selection of appropriate eyewear for a specific application is a choice of the user. Laser protective filters used as viewing windows in laser equipment or incorporated into optical instruments such as operating microscopes and loupes that may be used for deliberate viewing of laser radiation as part of their function are outside the scope of this document. NOTE Laser radiation in the wavelength below 180 nm is absorbed in air, therefore eye and face protection should not be required. This document is applicable to devices intended for patient protection during medical laser procedures except for treatment in the periorbital area. Guidance on patient protectors (including those used for periorbital treatment) is given in ISO TR 22463. The protectors described in this document are intended for use at ambient temperatures of (23 ± 5) °C, unless specified in particular requirement(s).
