Rayleigh Optical Corporation is a worldwide supplier of large custom optics for astronomical observatories, universities, government and industry.

Established in 1987, ROC has been providing custom optics for telescopes, instruments, and optical systems up to 2-meters in diameter.

ROC has extensive experience in fabricating high quality optics and components including: telescope optics (primary and secondary mirrors), lenses, spheres, LIDAR systems, holographic null optics and null lenses.

Optics for instruments include: Spectographs, Wide-Field Correctors, Atmospheric Dispersion Correctors, Collimators, Beam expanders, and holographic test plates.

ROC specializes in high quality Aspheres, Convex, Concave, Off-axis, Reflective and Refractive.

ROC has the capability to work with all types of optical materials including ultra-lightweight glass materials (ULE, Zerodur, Borosilicate), metal, plastic, and single crystal silicon.

Whatever the optical designer can dream up (and many have great imaginations!) we can probably find a way to fabricate it.

You can have the best seeing, a great camera, a good mechanical structure but IF you don’t have the BEST optics….you are not going to be able to optimize your system.

We believe the astronomy community deserves the best and so we give them the BEST, the Finest in Precision Optics.

We have the knowledge, the know-how and the experience!

Do not hesitate to contact us with any questions you may have, even if your project is not fully funded yet.
