AstroSolar® Safety Film 5.0 – Telescope Quality

Premium Solar Protection for Observation & Imaging

AstroSolar® Safety Film 5.0 is the gold standard for safe solar observation and high-magnification imaging. Designed specifically for telescopes, binoculars, and camera lenses, this premium film provides optical density (OD) 5.0 protection, making it completely safe for direct visual observation (when properly mounted) and solar photography.

Unmatched Optical Precision

Unlike other solar filters, AstroSolar® is engineered to maintain the optical wavefront without distortion. Interferometric tests confirm Strehl ratios of 94–96%—performance on par with fluorite triplet lenses by Carl Zeiss and Astro-Physics. It consistently delivers exceptional image sharpness and contrast.
