Request InfoNIDEK CO. LTD.The OPD-Scan II ARK-10000 optical path difference (OPD) scanning system for human vision assessment has been unveiled by Nidek Co. Ltd., providing information on corneal topography, autorefraction, keratometry and pupillometry. The system uses the principles of skiascopic phase difference for refractive error map measurement. The retina is scanned with an IR light slit beam, and the reflected light is captured by photodetectors. With the Placido disk technology, the system captures the image of reflected rings of light from the cornea and analyzes the data points to plot the corneal contour,...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra July 2023 IssueLaser Scanning Measurement SystemThe 3DS3000, a modular 3D laser scanning measurement and inspection system from Bold Laser Automation Inc. is designed for quality assurance processes.
