Request InfoCelera Motion, Westwind Air Bearing SpindlesWestwind Air Bearings Ltd. is offering the Poly625, a line of polygon scanners that require an air supply and that operate as fast as 40,000 rpm. Three standard polygon bearing designs are available to accommodate various speed requirements and mirror sizes. The company says that the devices are more efficient and deliver higher scan frequency and better optical quality and repeatability than typical scanners, and produce no backlash. They contain no contacting parts, resulting in low vibration and friction, fewer in- and cross-scan errors, and longer life. The scanners are fitted with an...See full productRelated content from Photonics MediaARTICLESPhotonics Spectra June 2023 IssueOptical Switching Technique Sets Ultrafast Bar for Data CommunicationsResearchers working as part of a multi-institution collaboration led by University of Arizona assistant professor Mohammed Hassan achieved what they said are previously unattainable data transfer...WEBINARSPhotonics.com 1/12/2023A Proven, Portable, and PIC-Based Methodology for Cultivating a Next-Generation WorkforceWith the passage of the CHIPS and Science Act and growing demand for photonic integrated circuit technology, the semiconductor industry is once again gaining momentum.
