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.)
