This patened film is being produced for visual and photographic solar observation at high magnification. 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 – 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 light blocking properties of AstroSolar™ SafetyFilm have been verified by the German Bureau of Standards (PTB) to be 99,999%. Conformity with existing EU-regulations for eye safety are certified by the CE-Symbol.

The optical density of OD 5.0 means that solar radiation intensity is being reduced to 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 since more than 15 years.
