ROC utilizes rigorous optical testing methods using phase-measuring inteferometers to measure the figure of the optical surface to demonstrate to the customer the optical specifications desired by the project have been met. We utilize several different software packages to enable us to provide a wide range of analysis of the measurement data.
ROC is pleased to offer this as a contract service, should your project only require verification of the optical surface or an optic finished with no data.
Sometimes testing for verification requires a test tower modified to specifically support the testing of the surface. ROC has several test towers able to test mirrors up to 2-metes in diameter and with a radius of curvature less than 8 meters.
ROC also has test towers specifically designed to test lenses up to 800 mm in diameter.
Secondary mirrors for telescopes, typically with convex non-spherical surfaces can also be measured in one of our test towers designed for testing and verification of secondary mirrors. Mirrors up to 1.5 meters can be tested in this tower.
Other testing methods used include: Null optics, Holographic null lenses, Swing arm Profilometry, and Sub-aperture stitching of both concave and convex surfaces using test plates.
We have the knowledge, the know-how and the experience!
