2-D detector using 256-element photodiode with visible sensitivity

C4675 series is a two-dimensional detector using a 16 × 16 (256) element Si PIN photodiode array that has high sensitivity in the visible range.

Current-to-voltage conversion amplifiers in the signal amplifier section are connected in parallel to each element of the photodiode array, thereby allowing high-speed parallel signal processing.

C4675 series is also designed to suppress the power consumption so it operates from two power supplies (±15 V).
