Plano Optics — Key Capabilities
At ITT We Can...
- Shape and grind plano surfaces on optics up to 100 inches (2.5m) in diameter, in both solid and lightweight configurations. Complex part geometries can be machined with our CNC waterjet cutter or CNC milling systems.
- Polish plano configurations in glass, glass ceramic and crystaline materials in 10 to 50-inch (0.25 to 1.25m) diameter optics with a figure accuracy better than 0.02 wave rms (0.01 microns rms).
- Achieve surface finishes of less than 2 angstroms on glass and glass-ceramic materials.
- Tune our processes to meet demanding requirements for spatial frequency errors, mounting needs and other application-specific issues of our customers.
- Utilize specialized test systems, including a Ritchie-Common test facility that allows full aperture testing of optics up to 72 inches (1.8m) in diameter and a 35-inch (0.9m) aperture Fizeau interferometer system. We also have phase measuring interferometers up to 24" (0.6 m) aperture capability.
- Incorporate state-of-the-art computer controlled figuring systems, such as small-tool polishing and ion figuring.
