MEASUREMENT PRINCIPLE
The OPM500 series of optical power
monitors employs photodiodes to measure
optical
power.
Precision
dual
transimpedance input stages provide for
high common mode rejection and linearity
throughout the full dynamic range of the
system.

FIELDS OF APPLICATION
These optical power monitors are
particularly useful for the measurement
and monitoring of optical power in the
standard telecommunications bands. The
output is a voltage linearly proportional to
power. The fast response time at high
signal-noise-ratio makes the OPM500
series particularly useful in systems
control feedback loops, such as in fibre

alignment systems. The high sensitivity
and
wide
dynamic
range
allow
measurement of fibre coupled lasers and
LEDs alike.
Several options of photodiode material
and optical input, including free beam
input, make these units useful in a wide
range of applications including nontelecom metrology.
The proprietary auto-nulling function
allows up to 7V of offset nulling. This is
particularly useful for eliminating a DC
signal component to concentrate on signal
changes, such as during component burnin and life-time testing. Bandwidth
selection and output polarity are also
selectable
via
the
TTL-compatible
interface.
