Pinholes do appear, but to 1 out of 10000 only in optical density 2.5! Baader AstroSolar™ safety film has been approved for eye safety by the National Bureau of Standards in Germany, the PTB. Unlike any other Solar Filter on the market, AstroSolar™ is CE-tested according to EG-Norm 89\/686 and EN 169\/92 ( notified body 0196). All processes connected to this product have been thoroughly tested. Coatings are inspected constantly for consistency to ensure your eye safety!\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan class=\"text\"\u003e \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan class=\"text\"\u003eBaader AstroSolar™ film Filter cell constructed from lightweight 18Ga. aluminum and powder coated white.
