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.
