Safety Note

For front-mounted use only on optical instruments. Not for direct eye viewing or use as eclipse glasses. This filter safely reduces solar intensity to ND5 levels for telescopes, cameras, and spotting scopes. ISO 12312-2:2015 applies only to handheld and eyewear solar viewers; therefore, this filter is not certified under that standard but is manufactured to meet ND5 safety requirements for optical filters.
