| PHOTODIODE 16 x 16 element photodiode array detector C4675 series 2-D detector using 256-element photodiode with visible sensitivity C4675 series is a two-dimensional detector using a 16 x 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 Applications l Wide spectral response: 400 to 1000 nm l Wide active area: 17.45 x 17.45 mm (0.95 x 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. l Nerve potential measurement under microscope l 2-D (wavelength x spatial position) spectrophotometry in visible range l Fine-modulation light measurement s General ratings Parameter Photodiode Number of element Active area (per 1 element) Element pitch Output type Dimensional outline Weight Rating Si PIN photodiode array (Made by Hamamatsu S4529) 16 x 16 (256) 0.95 x 0.95 1.1 Current-to-voltage conversion method, 256-ch parallel analog voltage output 136 (W) x 136 (H) x 153.5 (D) 2.1 Unit mm mm mm kg s Absolute maximum ratings Parameter Operating temperature Storage temperature Supply voltage Symbol Topr Tstg Vs Value 0 to +50 -10 to +60 (no condensation) 18 Unit C C V s Electrical and optical characteristics (Typ.

Under this condition, the output of C4675 series was monitored by FFT while sweeping the LED drive frequencies. LED HAMAMATSU C4675-xxx Vo FFT SWEEP GENERATOR KACCC0002EA 16 x 16 element photodiode array detector s Operating principle When light enters a photodiode, photoelectric conversion occurs in the photodiode and the photocurrent Ip is generated. The photocurrent Ip then flows through the current-tovoltage conversion amplifier feedback resistance Rf and is output as voltage V (=Ip x Rf). C4675 series uses current-to-voltage conversion amplifiers connected to each of the 256-element photodiodes to perform parallel signal processing. A low noise bias circuit is also used to reduce the photodiode junction capacitance.
