Non-Contact Thickness Measurement - Bristol Instruments
Bristol's non-contact thickness gauges utilize the unique properties of light to precisely measure the critical parameter of thickness. Both hard and soft transparent and semi-transparent materials are analyzed without damage or deformation. Measure thickness of optical components and lens assemblies, contact and intraocular lenses, displays, medical products, semiconductors, and glass. Learn more by scheduling a virtual demonstration.

Laser-Writing Method Facilitates 10,000× Greater Data Storage than Blu-Ray Disc
University of Southampton researchers have developed a fast and energy-efficient laser-writing method for producing high-density nanostructures in silica glass. The resulting tiny structures can be used for long-term five-dimensional (5D) optical data storage that is more than 10,000× denser than Blu-ray optical disc storage technology.
