Request InfoQED Technologies Inc.QED Technologies Inc. has released the SSI-A, a metrology tool for aspheres. It makes full-aperture interferometric measurements without the need for dedicated null lenses by taking several subapertures over the entire work surface and stitching the results together into a lattice to synthesize a full-aperture map. It automatically selects an appropriate transmission sphere; defines the lattice; measures wedge, centration and radius; moves the workpiece and nulls the interference fringes; and automatically sets the pixel scale setting, without lateral calibration. It measures almost any...See full productRelated content from Photonics MediaPRODUCTSPromoted Content March 2023 IssueCustom Precision OpticsSince 1947, three generations of family leadership have positioned LaCroix Precision Optics as the premier manufacturer of precision optics in America.
