Powered via USB port, USB 2 High Speed-compatible LaserCam-HR II cameras use BeamView software and are suited for production and laboratory settings. CCD sensors (½ and 2/3 in. formats) and circuitry lower noise floor and allow increase in bit-depth of image digitization process. Consequently, this optimizes dynamic range of camera and promotes laser beam diameter measurement sensitivity and accuracy, especially involving D4sigma and second moment calculations.
