Seiler Instrument

Seiler Instrument is a long-established private U.S. manufacturer and distributor of precision optical products, contract manufacturing services, and specialty equipment. Within healthcare, its Seiler Medical business supplies commercial medical and dental visualization devices including surgical microscopes, colposcopes, ENT and audiology microscopes, laboratory microscopes, and surgical loupes. The broader company also operates in precision manufacturing, geospatial, planetarium, and related technical markets rather than drug development. It appears to be an active family-owned company headquartered in the St. Louis, Missouri area and founded in 1945. For biotech and pharma diligence purposes, Seiler Instrument is best categorized as a commercial medical optics/device company, not a therapeutics developer.
