MODULE
Photosensor amplifier
C6386
Light-to-voltage conversion amplifier with optical fiber
Features
Built-in photodiode allows easy detection of light just by
connecting to a voltmeter.
l
Optical fiber light input
Measures light at a narrow detection point. Separating the
amplifier from the detection point allows measurement in
unusual environments and achieves low noise.
l
Three sensitivity ranges
Applications
l
Easy handling
l
Optical power meters
l
Laser monitors
l
Precision photometry
l
Various light detection (sparks inside equipment, etc.)
