Are the Solar Filters safe?

Yes. All of our Glass and Thin Film Solar Filters are safe for unlimited visual use and photography. Helios Solar Film and Helios Solar Glass® have been tested and meet the requirements for ISO 12312-2.

These filters block 99.999% of the sunlight and therefore are rated with a neutral density of 5. Careful handling and proper maintenance will ensure a long filter life.
