Features
l Easy handling
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
l High-speed response
Applications
l Optical power meters
l Laser monitors
l Precision photometry
l Various light detection (sparks inside equipment, etc.)
