The film is mounted stress-free, preventing any damage to the coating. The high-quality frame has rounded edges that protect the film. In addition, the underside of the film is made of a plastic with the same coefficient of thermal expansion as the film itself. This ensures that heating by sunlight does not generate tension between the film and the filter.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan dir=\"auto\"\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cb\u003e\u003cspan dir=\"auto\"\u003epackage\u003c\/span\u003e\u003c\/b\u003e\u003cspan dir=\"auto\"\u003e\u003cspan\u003e \u003c\/span\u003eincludes centering pins with screws and washers.
