IMAGE SENSOR CCD area image sensor S8844-0909 512 × 512 pixels, Back-thinned FFT-CCD S8844-0909 is an FFT-CCD area image sensor developed for measurement of low-light-level. S8844-0909 has a back-thinned structure for detecting light from the backside that allows high sensitivity from UV to near infrared region. S8844-0909 also delivers a wide dynamic range and low dark current when operated in MPP (Multi Pinned-Phase) mode. Spectral response characteristics are very stable making high-precision photometry possible. A one-stage thermoelectric cooler is built into the package along with the CCD chip. The CCD operating temperature can be maintained at -10 ˚C when used at room temperature (25 ˚C). S8844-0909 is identical performance and pin compatible with S7171-0909. S8844-0909 has wider FOV (Field of View) than S7171-0909 because of window structure.

It should be noted that this value is not the damage threshold value. To protect the thermoelectric cooler and maintain stable operation, the supply current should be less than 60 % of this maximum current. *14: Temperature of the cooling side of thermoelectric cooler. *15: Temperature of the heat radiating side of thermoelectric cooler. *16: Maximum heat absorption Qmax. This is a theoretical heat absorption level that offsets the temperature difference in the thermoelectric cooler when the maximum current is supplied to the unit. (Typ.

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 Element cooling/heating temperature incline rate should be set at less than 5 K/min.
