IMAGE SENSOR CCD area image sensor S9970/S9971 series Low dark signal · low readout noise/front-illuminated FFT-CCD 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. The S9970/S9971 series have an effective pixel size of 24 × 24 µm and are available in image areas ranging from 12.288 (H) × 1.44 (V) mm2 (512 × 60 pixels) up to a large image area of 24.576 (H) × 6.048 (V) mm 2 (1024 × 252 pixels). S9970/S9971 series are pin compatible with S7010/S7011 series. (Operating conditions are a little bit changed from S7010/S7011 series.) Features Applications l Low dark signal: 10 e-/pixel/s Typ.

In addition, wear anti-static clothing or use a wrist strap, in order to prevent electrostatic damage due to electrical charges from friction. ● Avoid directly placing these sensors on a work-desk or work-bench that may carry an electrostatic charge. ● Provide ground lines or ground connection with the work-floor, work-desk and work-bench to allow static electricity to discharge. ● Ground the tools used to handle these sensors, such as tweezers and soldering irons. It is not always necessary to provide all the electrostatic measures stated above. Implement these measures according to the amount of damage that occurs. ■ Element cooling/heating temperature gradient rate When using an external cooler, the element cooling/heating temperature gradient rate should be set at less than 5 K/min.
