The 49132 UV Protective Face shield is designed to protect the face area from harmful ultraviolet radiation. Our 1000 W and 1600 W light sources can emit extremely high levels of UV radiation. Goggles alone will not protect the user. We strongly recommend that all personnel operating our high intensity UV sources wear a UV protective face shield, in addition to gloves and clothing, so that there are no exposed areas of the body. Take particular care of the neck and wrists, as these are parts that are often inadvertently exposed. This UV protective face shield absorbs UV radiation from 200 to 405 nm. The shield is 8 x 14 in. (203 x 356 mm), and 0.080 in. (2 mm) thick. The minimum Optical Density (OD) is ~2.93 at 400 nm and a maximum OD of 4.36 at 265 nm.
