s Optical Characteristics (continued)
Note 3) Saturation output voltage:
This is the output voltage at the point beyond which it is not possible to maintain the linearity of the photoelectric
conversion characteristics as the exposure is increased. (The exposure at this point is called the saturation exposure.)
Note 4) Saturation Exposure (SE)
This is the exposure beyond which it is not possible to maintain the linearity of the output voltage as the exposure is
increased. When designing the equipment using these devices, make sure that the incident light exposure is set with
sufficient margin so that the CCD never gets saturated.
Note 5) Dark signal output voltage (VDRK)
This is defined as the average of the output from all the valid pixels in the dark condition at Ta=25˚C, Tint=10ms.
Normally, the dark signal output voltage gets doubled for every 8 to 10˚C increase in Ta and is proportional to Tint. The
dark signal output voltage (VDRK2) on the OS2 side will be larger than the dark signal output voltage (VDRK1) on the OS1
side because there is a delay memory on the OS2 side.
Note 6) Dark signal non-uniformity (DSNU)
This is defined as the difference between the maximum value among the output voltages of the all valid pixels at
Ta=25˚Cand Tint=10ms and VDRK.
Note 7) Dynamic range (DR)
This is defined by the following equation.
Since the dark signal output voltage is proportional to the accumulation time, the dynamic range becomes wider when the
accumulation time is shorter.
