MEASUREMENT PRINCIPLE
The OPM400 series of optical power
monitors employs photodiodes to measure
optical power. Precision single ended
transimpedance input stages to provide for
low offset and high linearity throughout the
full dynamic range.
FIELDS OF APPLICATION
OPM400englRevB.doc
These optical power monitors are
particularly
useful
for
the
linear
measurement and monitoring of optical
power. The fast response time at high
signal-noise-ratio makes the OPM400
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, make these units useful

• Quality control
in a wide range of applications including
non-telecom metrology.
These amplifiers have a particularly high
sensitivity and large dynamic range. There
are 16 gain ranges covering 5 decades of
gain in a 1-2-5 pattern. The gain-to-gain
accuracy of <1% allows confident
measurements of power curves over the
full range of sensitivity of the device:
6½ decades of measurement range. Thus
even very demanding measurements such
as the accurate and high speed, real-time
determination of polarization extinction
ratio becomes a simple task.
The OPM400 series is insensitive to
electromagnetic interference by design, an
important factor when working in „dirty“
industrial environments. These units are
provided in OEM-style enclosures. The
case wings provide for mounting on
standard 25mm and 1“ optical table tops
and for OEM applications.
