GOODRICH Electro-optical Systems

Electro-Optical Systems (EOS) is a worldwide leader in the design, development and manufacture of precision optics and electro-optical systems for defense, aerospace, scientific, and industrial applications. EOS has a 50-year heritage as part of The Perkin-Elmer Corporation, eight years as Hughes Danbury Optical Systems, and over two years as Raytheon Optical Systems, Inc. Goodrich purchased the business in March 2001 to complement its growing aerospace segment.


Products generally fall into two categories: sensor systems and optical systems. In addition, EOS conducts advanced technology studies and performs technology demonstration experiments in the fields of optics, electro-optics, and spectrometric sensors.

Sensing products include threat warning receivers, spacecraft guidance sensors, and airborne vehicle support system sensors. The laser warning business includes air- and ground-based products including the AN/AVR-2A (airborne) and 218S and 318S (ground) Laser Warning Receiver systems fielded by both U.S. and international military forces. Spacecraft guidance sensors include the Hubble Space Telescope Fine Guidance Sensor, and precision guidance and attitude sensors for space and airborne platforms including the HD-1003 Star Tracker and 13-410 Multi-Mission Earth Sensor.

The company also produces space borne electro-optical systems, telescopes, precision optics, and customized optical windows, filters and coatings. We specialize in surveillance and directed energy systems with emphasis on visible light sensors, optical systems, and various multi-spectral electro-optical sensors. EOS also produces adaptive optics systems for atmospheric compensation and various beam control applications. Precision optics capabilities include optics ranging from millimeters to 10+ meters in spheric and aspheric configurations, and include design, manufacture and test of optics as well as optical assemblies. The optics for the Hubble Space Telescope, the Chandra X-Ray Observatory, and the Space Infrared Telescope Facility were designed and manufactured in Danbury.

Facilities and Resources

The 535,000-square-foot facility is an integrated design, manufacturing, and test site, certified to ISO 9001 standards. EOS offers a world-class optics fabrication and test facility, all located under one roof, and designed and operated to the most stringent customer requirements.

Manufacturing facilities include computer-controlled grinding, polishing, and lightweighting featuring a 67-foot metrology tower capable of handling optics up to 4 meters in diameter; computer-controlled grinder/polishers with 5-axis control to 30 ┬Ám accuracy for metals, glasses and composites; a laser profilometer and contour measuring profilometers.

Coating operations have recently expanded into a world-class, state-of-the-art facility with over 20 coating deposition chambers for ultraviolet, visible, and infrared applications.

Environmental tests are conducted in special facilities for vibration, acoustic, high altitude vacuum and cryogenic thermal environments simulating the most severe requirements.

Production manufacturing features state-of-the-art detector and circuit board fabrication, optical manufacturing, and opto-mechanical assembly operations. The employee count at Wooster Heights is now at 564.
