ROCHESTER, NY, Feb. 12 -- Melles Griot Optics Group announced it recently commissioned installation of its QED Q22-Y magnetorheological (MRF) finishing system and large-aperture, digital phase-measuring interferometer at its Rochester, N.Y., manufacturing complex, in a new class-10,000 clean facility. The company said the system will enable it to produce spherical surfaces accurate to 1/250 of a wavelength, root-mean-square (rms), at 632 nm, using the "3-sphere" calibration method. The system uses a computer-directed, electromagnetically controlled "ferro-fluid" polishing method to...Read full articleRelated content from Photonics MediaArticlesIncreased Component Density Plants Hurdles on the Road to Scaling the Production of PICsWhen CEO Iñigo Artundo’s company began providing engineering solutions for photonic integration in 2011, the typical photonic integrated circuit (PIC) had five to 10 components.
