Request InfoPolytec Ltd.Polytec Ltd. has introduced a scanning laser vibrometer for study of complex structures. The PSV-500-NB Scanning Vibrometer (Notebook) allows noncontact, zero-mass-loading measurements, making it suitable for examining lightweight surfaces, as well as hot, cold and dangerous surfaces. Deflection shapes can be color coded as 2-D or 3-D graphics for display purposes. Frequencies of interest are selected from the spectra using a cursor. The video image can be animated in 3-D to show exaggerated, lifelike motion of the structure. Animated profile slices also help users understand the...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 10/4/2023Digital Sampling OscilloscopesThe DSO-1000 series from Quantifi Photonics are digital sampling oscilloscopes that target applications across 100 - 800 G and 1.6 T ethernet, emerging co-packaged optics and in-package optical I/O,...Vision-Spectra.com June 2022 IssueFluorescence Imaging SolutionThe Fluorescence Imaging Solution from TPL Vision UK is a multi-UV dome device, bringing safety and flexibility to UV fluorescence imaging applications.
