Tungsten Eye Shields can use either the 0.5 mm or 1 mm thick anodized aluminum cap (both are included with each tungsten eye shield) to reduce the electron backscatter to the eyelid. The eye shield can be used without the aluminum cap when placed superficially. Tungsten eye shields have less transmission than other eye shields. The 2 mm tungsten eye shield is recommended for use with 6 MeV. The 3 mm tungsten eye shield is recommended for 9 MeV. These tungsten eye shields are not recommended for use above 9 MeV. The user will have to determine an acceptable amount of backscatter to decide whether to use 0.5 mm or 1 mm aluminum cap.
