Precision instruments have been a Seiler family tradition since 1913 when company founder, Eric H. Seiler entered the ZEISS School of Fine Optics in Jena, Germany. After earning a Master’s degree in Fine Optics, Eric H. Seiler brought his craft to the United States where he and his wife, Dora L. Seiler, started Seiler Instrument and Manufacturing Company. With Eric H. Seiler’s knowledge of optics, and his son Eric P. Seiler’s knowledge of business, the company flourished. Since 1945 Seiler Instrument and Manufacturing has been bringing the customer’s ideas to life.

The Seiler Manufacturing Division product line consists of optical instruments, assemblies and subassemblies, and machined parts. Seiler is the Original Equipment Manufacturer for the optical fire control used on all United States howitzer and mortar systems. We supply these products and services directly to agencies of the U.S. Department of Defense under prime contracts, to other prime contractors as a subcontractor, and to international customers, both directly and under the U.S. government’s Foreign Military Sales Program.

Seiler stays current with new technology by adding sophisticated tools and machines every year. Although CNC machines have replaced manually operated machines, there is still no replacement for old-world craftsmanship, a necessary attribute of every instrument manufactured by Seiler Instrument. Technology may change, but one thing continues to endure – Seiler’s dedication to quality excellence and customer service, a philosophy that breeds customer satisfaction.
