Back-thinned FFT-CCD The is a family of FFT-CCD image sensors specifically designed for low-light-level detection in scientific applications. By using the binning operation, the can be used as a linear image sensor having a long aperture in the direction of the device length. This makes the 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 also features 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 has an effective pixel size of 24 24 μm and is available in image areas ranging from 2.288 (H).392 (V) mm 2 (52 58 pixels) up to a large image area of 24.576 (H) 2.928 (V) mm 2 (24 25 pixels).

Precautions (electrostatic countermeasures) Handle these sensors with bare hands or wearing cotton gloves. In addition, wear anti-static clothing or use a wrist band with an earth ring, 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 incline rate When cooling the CCD by an externally attached cooler, set the cooler operation so that the temperature gradient (rate of temperature change) for cooling or allowing the CCD to warm back is less than 5 K/minute.
