Abstract:

Six types of laser protective eyewear were evaluated in terms of their optical properties and spectral characteristics. These six types cover the protection for almost the entire visible spectrum. Type GG-9 and Type OG530 can be used to protect the He-Ne laser 633 nm, type OG-590 and type RG-610 are for argon laser 500 nm. Type BG-18 is for Ruby laser 694 nm and type KG-3 are for Nd glass laser 1060 nm or CO2 laser 1060 nm. The optical properties and spectral characteristics are investigated by means of average and full spectral transmittance as well as their corresponding CIE chromaticity coordinate values. Results suggested that one type of the protective device should be used only for the specific laser. Furthermore, the device should not be used when a detection of a chromatic display or light source is required.
