Product Description

Universal Solar Filters (ULF) are easy-to-assemble cardboard filter kits created for safe solar observation. Powered by Thousand Oaks' renowned SolarLite filter material, once assembled, the filter mounts over your optical lens to reduce sunlight intensity to a safe level, revealing clear views of the solar photosphere and active sunspots.

The ULF-70 model features a 70mm free optical aperture and is engineered to fit housing outside diameters ranging from 65mm to 80mm. It fits most standard professional camera lenses (including those accepting 77mm filter threads) as well as numerous popular spotting scopes and binoculars. For optical bodies with smaller outer diameters, the mounting tabs can be easily folded inward to secure a tight grip on the lens.
