…with all of its LaserCamTM-HR camera-based beam diagnostics systems. In Depth: CCD versus CMOS Cameras and CAPTTM Technology The two most commonly used cameras in beam profiling utilize Charge-coupled devices (CCD) or Complementary metal-oxide- semiconductor (CMOS) sensors. Each has unique strengths…
…generation of digital USB 2.0 bus-powered, high-resolution, large-area cameras. The LaserCam-HR II family includes 1/2-inch and 2/3-inch format CCD cameras that provide greater dynamic range and lower noise than the previous generation. The cameras include Coherent's BeamView software package,…
…shows the main components used in this successful HHG demonstration. The HHG was
analyzed using an EUV imaging spectrometer followed by a EUV CCD array detector. When argon

…excitation, but may need a photomultiplier tube or a CCD array when used with a LED source. For instances where a laser-based instrument uses a room- temperature CCD array, the LED version of the same instrument might need an actively-cooled CCD array. Unit-to-Unit Variability - Supply Chain…
…explains that the Shack-Hartmann
wavefront measurement method is pretty simple.
"It is based on the association of a lenslet array with a 2D CCD
type of detector in its focal plane," he says. "The method consists
of measuring local wavefront derivatives in real time. Imagine's…

at other wavelengths. Together with CCD and then CMOS cameras, this enabled compact and
efficient experiments as well as integrated spectrometers and microscopes.
