Melles Griot, a supplier of photonics products, is using its new QED Subaperture Stitching Interferometer (SSI) to provide precise interferometric measurements of large clear aperture and high numerical aperture surfaces. The SSI will work in conjunction with a magnetorheological finishing system located in a class-10,000 cleanroom to produce the optical elements. The company expects the move to significantly increase the surface accuracy of the optical elements produced at its Melles Griot Optics Group facility. . . . RoseStreet Labs (RSL), a supplier of products and services for wireless infrastructure and sensors in the life science, renewable energy and homeland security markets, announced the opening of its 3-D research and development laboratory for semiconductor packaging. RoseStreet Labs and its subsidiary, FlipChip International, known for its flip chip and wafer level packaging product lines, are located in Phoenix, Ariz. RSL also announced an alliance with Suss MicroTec, with the company's full suite of lithography and 3-D packaging equipment selected for RoseStreet's laboratory.
- An instrument that employs the interference of lightwaves to measure the accuracy of optical surfaces; it can measure a length in terms of the length of a wave of light by using interference phenomena based on the wave characteristics of light. Interferometers are used extensively for testing optical elements during manufacture. Typical designs include the Michelson, Twyman-Green and Fizeau interferometers.
The basic interferometer components are a light source, a beamsplitter, a reference...
