Photodiode module

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)
