Request InfoPrecision Laser Scanning LLCSCOTTSDALE, Ariz., Sept. 8, 2016 — Precision Laser Scanning LLC has announced the Precision Start-of-Scan Detector for polygon scan heads for materials processing. Working beams are controlled with an integral detector isolation tube that blocks stray light except for a small operating aperture. Should stray light entering the aperture cause interference, an optional band pass/reject filter can be installed in the tube, solving the optical interference problem. The detector uses a temperature-compensating bi-cell sensor to eliminate thermal drift accuracy error.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/20/20223D PrinterThe Sapphire XC 1MZ 3D printer from Velo3D Inc. allows users to print parts with a height of 1 m, increasing the addressable use cases of end-to-end metal additive manufacturing.
