Request InfoNational Aperture Inc.The Pow-R-Ring laser beam delivery system from National Aperture Inc. can drill holes in metals and ceramics up to 0.10 in. thick with tolerances of less than ±0.001 in. The device uses laser power optics technology to enable formation of visible region laser beams into a ring to meet exact diameter and taper requirements. The company says the Pow-R-Ring provides a cleaner, rounder hole edge of consistent size and has five to 10 times the drilling speed.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/8/2023Active Optical CablesAn active optical cable (AOC) family is designed for disaggregated data center and cloud environments.
