Photodiode module
C10439 series
Integrates a Si photodiode for precision photometry with low-noise amp
C10439 series photodiode modules are high-precision photodetectors that integrate a Si photodiode and a current-to-voltage amplifier. 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. C10439 series is available with three different active areas.
