*8: Maximum current Imax:
If the current greater than this value flows into the thermoelectric cooler, the heat absorption begins to decrease due to the
Joule heat. 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.
*9: Temperature of the cooling side of thermoelectric cooler.
*10: Temperature of the heat radiating side of thermoelectric cooler.
*11: 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.

s Specifications of built-in temperature sensor
A chip thermistor is built in the same package with a CCD chip, and the CCD chip temperature can be monitored with it. A relation
between the thermistor resistance and absolute temperature is expressed by the following equation.
R1 = R2 × expB (1 / T1 - 1 / T2)
where R1 is the resistance at absolute temperature T1 (K)
R2 is the resistance at absolute temperature T2 (K)
B is so-called the B constant (K)

(Typ. Ta=25 ˚C)
The characteristics of the thermistor used are as follows.
R (298K) = 10 kΩ
