Measurable incident light level

CMOS image sensor built into the C12666MA has a large saturation charge, and that built into the C12880MA has a large charge-to-voltage conversion gain. To perform high S/N measurement, the C12666MA is recommended when the incident light level is high and the C12880MA when the level is low.

Input spot diameter: 800 m (λ=550 nm)
The measurable light level is calculated from the settable integration time.
The settable integration time is different between the C12666MA and C12880MA.
The S/N during measurement is not taken.
