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).

Features

l Wide spectral response: 400 to 1000 nm

l Wide active area: 17.45 × 17.45 mm

(0.95 × 0.95 mm per element, 1.1 mm pitch)

l Frequency response C4675-102: DC to 1 kHz

C4675-302: DC to 3 kHz

C4675-103: DC to 10 kHz

l Parallel signal output by current-to-voltage amplifier

l Low power consumption: 2.5 W Typ.

Applications

l Nerve potential measurement under microscope

l 2-D (wavelength × spatial position) spectrophotometry

in visible range

l Fine-modulation light measurement
