The patened Baader AstroSolar® Safety Film 5.0 is being produced for visual and photographic solar observation at high magnification (with additional optics). 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
When using AstroSolar® Safety Film 5.0 – mounted in front of your optics – you can image the Sun and safely look through the viewfinder of your camera – or you can directly look into the Sun with telescopes and binoculars at any suitable magnification.
The coating of AstroSolar® Safety Film 5.0 is subject to constant quality control. Its reflective property and security for solar observation through optical instruments is being tested repeatedly.
AstroSolar® Safety Film 5.0 reduces the intensity of solar radiation by 99,999% to a factor of 1 : 100 000 of the initial value. Multiple coating processes on both sides of the carrier film are adding up during production to result in a perfectly uniform filtering result and help in neutralizing the effect of microscopic pores in the coating hat plague conventional glass solar filters which are commonly only coated on one side of the glass.
One single layer of AstroSolar® Safety Film is perfectly apt to enable production of a safe solar-filter, suitable to supply highest contrast and sharpness in combination with your telescope or camera tele-lens. We produce this diffraction limited filter material for more than 25 years.
Important note: The eye safety norm EN ISO 12312-2:2015 for naked eye solar viewers does not apply to front aperture filters, covering long-range optics. AstroSolar® Safety Film 5.0 is not authorized to be used for naked eye solar observation or production of solar viewers. For direct solar viewing without telescope, binocular or camera optics, inquire for our EN ISO 12312-2:2015 certified eclipse shades equipped with AstroSolar® Silver/Gold Film.
