For decades, Seiler has been connected to ZEISS through a shared commitment to precision, optical excellence, and long-term customer support.

From planetarium technology and projection systems to service, installation, and ongoing support, the Seiler and ZEISS relationship reflects what strong partnerships are built on: expertise, trust, and a commitment to doing the work the right way.

It is a connection that also ties back to Seiler’s own history, beginning with Eric H. Seiler’s roots in Jena, Germany, the same city known around the world for optical innovation and the ZEISS legacy.

Today, Seiler continues to support planetariums and customers across the country with the same focus on quality, service, and precision that has shaped the company for generations.
