Measuring up to NASA’s James Webb Space Telescope
The reason Twyman-Green was best
A Twyman-Green configuration of interferometer is capable of retaining light, and expanding to large spherical surfaces.
Three models of PhaseCam, a Twyman-Green interferometer with dynamic measurement capabilities.
NanoCam's 3D roughness measurement
Sub-Angstrom RMS precision makes NanoCam Sq the best choice for highly demanding roughness measurements of optical finish.
NanoCam inside glass machining CNC
Dynamic measurements enable quality assurance measurements in-line and within the manufacturing equipment. The dark blue T-shaped object behind the wet glass is a NanoCam Sq optical profiler.
