About this product
This transparent film will protect your valuable optical equipment, close telescope tubes against dust and humidity, greatly reduce air currents - all without reducing the optical quality of your telescope.
Baader Planetarium say: This is the essence of AstroSolar ™ safety film. A highest precision, crystal clear material (not "Mylar"). It is a monomer film which we found after thoroughly testing more than 200 different film samples on our Zeiss autocollimator. This film was used in German Science Institutes as optical membrane for nuclear and particle physics experiments. The basic substrate has been further refined and homogenised by a proprietary annealing process that was developed exclusively for us. Due to these treatments Turbo Film attains perfect homogeneity and performs equal to a 1/10 wave plane parallel optical window. In fact it has the lowest wedge error of any existing optical window.
