Simplify the Complex, with Verifire™ MST by ZYGO

Simplify the complex – multiple surfaces create complex fringe patterns, the Verifire™ MST uses patented wavelength-shifting technology to acquire phase data from multiple surfaces simultaneously. Report key metrics from individual surfaces of parallel windows, transmitted wavefront, as well as precise surface-to-surface information like total thickness variation (TTV), wedge and even material inhomogeneity. The Verifire™ MST…

Simplify the complex – multiple surfaces create complex fringe patterns, the Verifire™ MST uses patented wavelength-shifting technology to acquire phase data from multiple surfaces simultaneously. Report key metrics from individual surfaces of parallel windows, transmitted wavefront, as well as precise surface-to-surface information like total thickness variation (TTV), wedge and even material inhomogeneity.

The Verifire™ MST addresses demanding applications like mobile device display glass, data storage disks and semiconductor wafers with precise surface and thickness variation metrology for test parts as thin as 0.5 mm.

Zygo knows how important simultaneous measurements are for precision metrology. That's why we created the Verifier MST Fizot laser interferometer, which performs high quality measurements of multi surface cavities. Verify t is the only commercial interferometer system that can measure multiple surfaces simultaneously. Set up and alignment are seamlessly simple with software guiding you every step of the way. High precision surface form of playing parallel optics enabled by patented FTQPSI acquisition. Our advanced technology can qualify front surface, back surface, and optical thickness variation, all with just one data acquisition. Verifier MST can also perform homogeneous and total thickness variation metrology with only two surface acquisitions. Our powerful software suite enables data acquisition and analysis of hundreds of reportable parameters. Zygo offers leading hardware options including encoded zoom and focus, We also complete all design, manufacturing, and qualifying of our reference optics because we know you depend on high quality and guaranteed laser interferometer performance. Metrology without compromise. C y Zygo is the most trusted brand of laser interferometers today. Visit w w w dot zygo dot com for more information about the Verifier MST laser interferometer.

Room displays are now judged on management and platform fit, not just screen size

Room displays are now judged on management and platform fit, not just screen size

IndexBox says AV demand is no longer confined to periodic capital refresh cycles and that AV systems are increasingly embedded in daily workflows. A separate Research and Markets U.S. interactive whiteboard report (covering interactive whiteboards and interactive flat-panel displays) points to education demand for centralized device management and cloud connectivity, and to workplace demand for integration with Microsoft 365, Google Workspace and video conferencing platforms.

  • 01A display bolted to a classroom wall now gets judged like a laptop fleet: on how it is managed and connected, as much as on its screen.
  • 02Research and Markets says buyers are prioritizing centralized device management in education and tighter integration with Microsoft 365, Google Workspace and video conferencing in workplaces.
