CVI Technical Optics Installs 12-inch Interferometry Capability

CVI Technical Optics announced the installation of a 12-inch Zygo interferometer in its Isle of Man manufacturing facility. CVI Technical Optics has been fabricating and coating large format windows up to 520mm in diameter for many years and is the CVI "Center of Excellence" for large format optical components. This 12-inch interferometer is a significant upgrade of CVI's metrology capabilities.

Typical 6-inch beam expanded interferometers force manufacturers to provide "stitched" data, which is prone to significant errors for optics larger than 12-inches (305mm). Increasingly, new requirements mean that customers can no longer accept this data as certification of compliance.

"Over the years we have seen growth in the market for large optics. Now we can provide one-shot interferograms for optics up to 12-inch (305mm) clear aperture. This capability enables CVI Technical Optics to ensure precision specifications over large clear apertures, including flatness before and after coating. This investment on the part of CVI demonstrates our intention to become the leader in large format optics," states Helmut Kessler, CVI Technical Optics General Manager.

CVI will be at booth 940 during Defense and Security with copies of the CVI Catalog for Optical Components and Assemblies.
