S9970/S9971 series

The S9970/S9971 series are families of FFT-CCD image sensors specifically designed for low-light-level detection in scientific applications. The

S9970/S9971 series offer lower dark current and lower readout noise than the S7010/S7011 series that have been marketed. By using the

binning operation, the S9970/S9971 series can be used as a linear image sensor having a long aperture in the direction of the device length. This

makes the S9970/S9971 series ideally suited for use in spectrophotometry. The binning operation offers significant improvement in S/N and

signal processing speed compared with conventional methods by which signals are digitally added by an external circuit. The S9970/S9971 series

also feature low noise and low dark signal (MPP mode operation). This enables low-light-level detection and long integration time, thus achieving

a wide dynamic range.
