IMAGE SENSOR NMOS linear image sensor S9/S9 series Built-in thermoelectric cooler ensures long exposure time and stable operation. NMOS linear image sensors are self-scanning photodiode arrays designed specifically as detectors for multichannel spectroscopy. The scanning circuit is made up of N-channel MOS transistors, operates at low power consumption and is easy to handle. Each photodiode has a large active area, high UV sensitivity yet very low noise. The built-in thermoelectric cooler (air cooled) allows a long exposure time achieving a high S/N even at low light levels. The cap uses a sapphire glass window hermetically welded for high reliability.

Vscg Input Used for restricting blooming. This should be grounded. Vscd Input Used for restricting blooming. This should be biased at a voltage equal to the video bias voltage. Video output signal. Connects to photodiode cathodes when the Active video Output address is on. A positive voltage should be applied to the video line in order to use photodiodes with a reverse voltage. When the amplitude of φ and φ is V, a video bias voltage of V is recommended. Dummy video Output This has the same structure as the active video, but is not connected to photodiodes, so only spike noise is output. This should be biased at a voltage equal to the active video or left as an open-circuit when not needed. Vsub - Connected to the silicon substrate. This should be grounded. End of scan Output (CMOS logic compatible) - Should be grounded. TE-cooler Input For sensor chip cooling Thermistor Output For temperature control This should be pulled up at V by using a kω resistor. This is a negative going pulse that appears synchronously with the φ timing right after the last photodiode is addressed. Figure Spectral response (typical example) PHOTO SENSITIVITY (A/W).....
