Technical Information

 
Short Technical Description /Certifications
Baader Planetariums AstroSolarTM safety film is a specially manufactured streak- and blisterfree foil. It attains the optical performance of planeparallel glass filters. The base material is not "Mylar"!. The basic development of this film was made in laboratories for nuclear- and particle physics.

High density coatings on both sides of the foil ensures a highly uniform filtering, while neutralizing the occasional miscroscopic holes in the coating. The image of the sun is extremely contrasty and of almost neutral colour.

The coating of the foil is subject to constant quality control. Its reflective property of over 99.999% has been tested by a German Republic bureau of standards and conformity with EU norm 89/686 is certified with the CE-symbol. We deliver AstroSolarTM safety film in sheets of 20x29.5 cm. For larger requirements, such as instruments with larger aperture or high-volume orders, it may be obtained in rolled sheets of 100 x 50 cm (approx. 4 Sq.Ft).
