InGaAs photodiode C10439-15

Integrates photodiode for precision photometry with low-noise amp [Photosensitive area: 2.4 × 2.4 mm (Si), φ1 mm (InGaAs), built-in Two-color detector] The C10439 series photodiode modules are high-precision photodetectors that integrate a photodiode and a current-to-voltage amplifi er. The output from these photodiode modules is an analog voltage and can be easily checked with a voltmeter, etc. Since their sensitivity is switchable between two ranges (High/Low), highly accurate output can be obtained by selecting the proper sensitivity range that matches the light level to be detected. Features -Voltage output for easy handling -Two-range (High/Low) switching function -Compact: business card size -Can be mounted on optical bench rod (M4) Specifications Photosensitive area - 2.4 × 2.4 (Si), φ1 (InGaAs) mm Spectral response range - 320 to 2600 nm Peak sensitivity wavelength - 940 (Si), 2300 (InGaAs) nm Output - Analog Conversion impedance - Low range: 1 × 106 V/A High range: 1 × 105 V/A Cutoff frequency - Low range: 100000 Hz High range: 10000 Hz Supply voltage - ±5 to ±12 V Measurement condition - Ta=25 ℃, Vs=±12 V, unless otherwise noted
