About

About 603 OPTX 603 OPTX supports the satellite manufacturing industry with precision metal optics built for the realities of space. We specialize in ultra-precision diamond turned aluminum mirrors engineered for lightweighting, thermal stability, and repeatable performance in vacuum and vibration environments. From rapid prototyping to full production runs, our vertically integrated processes—diamond turning, advanced metrology, and finishing—allow satellite primes and subsystem integrators to move from concept to orbit with confidence. We routinely manufacture complex aspheres, off-axis parabolas, and freeform geometries for ISR, Earth observation, and space domain awareness systems. With tight control over material sourcing and process validation, 603 OPTX delivers optics that meet demanding schedules without compromising performance. Built in New Hampshire. Built for space.
