Request InfoFree Lynx Camera Software UpgradeImperx Inc.BOCA RATON, Fla., May 11, 2006 -- Vignetting -- falloff of image brightness with distance from the frame’s center -- and pixel-to-pixel CCD-sensitivity variations can be major problems for machine-vision systems used in inspection and motion-control applications. Imperx’s Lynx programmable cameras include software correction for these variations, based on an array of calibration coefficients measured during final product testing at their factory, but these coefficients cannot fully compensate for changes in vignetting when different lenses are used or pixel sensitivities change with age. To eliminate this problem, Imperx has...See full productRelated content from Photonics MediaPRODUCTSPromoted Content April 2024 IssueNanometer Precision AlignmentAerotech’s FiberMax®HP represents a significant breakthrough in the high-volume manufacturing and testing of photonics components, reflecting more than 40 years of experience in designing...Photonics Spectra October 2023 IssueCustom Air Bearing Motion SystemsCustom air bearing motion systems from Physik Instrumente LP are designed to enhance performance in various industrial applications such as photonics, medical design, aerospace, and semiconductors....Promoted Content April 2023 IssueGantries For Laser ProcessingPI offers XY and XYZ gantry positioning systems for laser processing, 3D printing, and photonics test and metrology applications.
