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 details behind the selection
Compare sensor configurations, coating options, operating limits and integration details directly below. Check the operating mode and temperature alongside each performance value.
