Our company’s history is defined by a dedication to excellence across generations. Everything can be traced back to our beginning in the early 1900s when our founder, Eric H. Seiler began pursuing his interest in fine optics.



Eric H. Seiler begins his studies at the Zeiss School of Fine Optics in Jena, Germany.

After receiving his master’s degree, Seiler and his wife Dora move to the United States and start the Seiler Instrument and Manufacturing Company.

After several years repairing and refurbishing existing equipment, Eric H. Seiler develops his own set of survey instruments for distribution.

Seiler is now manufacturing and distributing over 100 products which prompts the creation of the Manufacturing and Survey Divisions.

Eric. H Seiler partners with Carl Zeiss to distribute Zeiss’ line of microscopes in North America. Several years later, the successful partnership comes to an end, and Eric H. Seiler develops his own cutting-edge microscope line which leads to partnerships in Germany, South America and Asia.

The Planetarium Division is created when Seiler’s renews their partnership with Zeiss and distributes Zeiss Planetaria equipment throughout the United States and Canada.

Seiler acquires McMillan Night Vision and begins manufacturing and distributing day/night vision rifle scopes to the military, law enforcement and hunters.

President Rick Seiler, Executive Vice President Tom Seiler, and Executive Vice President Louise Schaper continue their family legacy of innovation and quality across six divisions: Precision Manufacturing, Geospatial, GeoDrones, Medical, Planetarium and Design Solutions.
