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.)
