• AstroSolar® Safety Film 5.0 for solar observation and photography at high magnification, telescope quality, Optical Density (OD) = 5.0
• Safe for visual solar observation (with additional optics) and imaging
• This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics
• AstroSolar Safety Film is best suited for precision work with all astronomical telescopes and binoculars – just as well as for all photographic camera- and tele-lenses
• For more than 25 years on the market, the only film-material made to not deteriorate the optical wavefront, it does allow to attain high magnification with any long-range optics without reducing sharpness or contrast of the solar surface.
