Request InfoHypertherm Inc.The LH1575 FastLaser, Hypertherm Inc.'s second CO2 laser cutting head based on flow-accelerated screen technology, offers expanded cut capacity and cut quality with a minimum 10% to 20% increase in cut speeds on thick mild steel. The patented process delivers optimal gas flow directly to the cut zone, matching beam width and gas flow geometry. Lens change is quick and requires no tools, and the focal length can quickly be adjusted between 5.0 and 7.5 in. The lens is gas-cooled, while the laser head and nozzle are water-cooled. Options include precentered optics and top-mount spring collision...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra September 2023 IssueBeam Profiling SystemThe Ophir® BeamWatch® Plus noncontact beam profiling system from MKS Instruments Inc. is designed for measuring focus shift, focus spot size, and position of high-power industrial lasers...Photonics Spectra August 2022 IssueConfocal SensorsThe Gocator® 5500 series of smart 3D line confocal sensors from LMI Technologies features a 3D smart sensor platform with next-generation, on-sensor, industrial Internet of Things web-based...Photonics.com 5/24/2023Scalable Computing PlatformAdvantech’s Valor Mini Workstation is a compact industrial PC built on a mini ITX motherboard that supports Intel 10th Gen Core i processors with the H420E chipset.
