In-vacuum CCD
Direct-detection CCD spectroscopy for VUV, EUV and X-ray experiments, with the complete detector operating inside the vacuum chamber.
From photon to signal
Select the sensor coating for the actual wavelength or photon energy. The plots below preserve the manufacturer’s axes, legends and response conditions.
Select a figure to inspect the original axes, legend and curves.
Original manufacturer curves for the sensor and coating codes shown in the legend. Match the selected code to the performance matrix; the curves are reference response data, not a guaranteed value at every wavelength. The direct-detection plots retain photon-energy and wavelength axes. The separate silicon electron–hole-pair plot is not a QE curve.

Plan the integration
Enlarge the mounting, connector and camera-outline drawings. Dimensions and model dependencies are retained.
Manufacturer drawing in the original units. Camera body, sensor location, ports and flange depend on the selected format and housing; use the model dimensions table to confirm the configuration.
Build your enquiry
Choose a published configuration, add the integration topics you want to discuss, and keep the exact model in your enquiry.
