Photonics Spectra
Mar 2009
QED Technologies Inc.Request Info
 
QED Technologies has unveiled its aspheric stitching interferometer, which measures steep aspheres with as much as 1000 waves (more than 600 μm) of departure from the best-fit sphere, without the use of dedicated null lenses or computer-generated holograms. The device is based on the company’s subaperture stitching technology.
