Precision Optics

For more than 50 years, L3Harris has provided high-performance optical components and assemblies for the world’s most sophisticated ground and space-based observation systems. Today we are the fabricator of choice for large, high-precision products that meet our customers’ most rigorous requirements.

Custom, Large-scale Optics

L3Harris provides optomechanical design, optical fabrication, test, and assembly capabilities for precision optics solutions and systems. We specialize in the custom fabrication of large optics up to 3.5 meters. For more than 50 years, we have fabricated large optical components, including both lightweight and solid mirrors in most geometric shapes, to meet low surface microroughness and tight surface figure error specifications. This experience, along with our rigorous metrology and testing program and our state-of-the-art in-house facilities, enable us to meet demanding quality and delivery requirements.

Key Capabilities

  • Polish aspheric, spherical, and flat surfaces in glass, glass ceramic, and crystaline materials up to 3.5 m with surface figure quality less than 10 nm RMS
