TSE17 was established for the Great Solar Eclipse in the United States of America in 2017. Over 12 million glasses were sold at that time. The company is one of the few suppliers of the required special filter films with which the glasses are made and which are mandatory for observation. The protective film is subject to the highest safety regulations and is ISO-certified.
In addition to solar eclipse glasses, TSE17 also offers its certified film individually for self-assembly. Information brochures and stickers on upcoming solar eclipses complete the offer.
