Count on High Performance
The OMM-6810B is an accurate, low noise
power meter capable of measuring optical powerover an 80dB dynamic range and offers thestability and repeatability necessary for precise
power measurement. Packed with other features
including a simple wavelength measurement
technique developed at ILX Lightwave, theOMM-6810B becomes the only power meter
to measure wavelength and power in a single,
easy to use instrument. Power/Waveheads
offer up to 10W of optical power measurementwith wavelength measurement accuracies fromseveral tenths of a nanometer to one nanometer.
For spectral measurements of high power sources,a fiber tap is included on the OMH-6780B, 6790B,
and 6795B Power/Waveheads to allow convenientconnection to an optical spectrum analyzer.

Semiconductor Power/Waveheads provide accurate
measurements of short wavelength lasers.

A Wide Variety of
Measurement Heads
The OMH-6700B Series Optical Measurement
Heads, when coupled with the OMM-6810B
Optical Multimeter, provide the flexibility to easily
and accurately measure the optical power of mostlaser diode sources available today including
short wavelength lasers, higher power pump, andfiber laser diodes. In addition, Power/Waveheads
are available that measure the power-averaged

sphere technology for both free space measurements
and fiber measurements. All measurement heads
can be configured for the most common fiber optic
connectors including FC, LC, ST, SC, and bare fiber.

Optical Powerand Wavelength
MeterPower Only Heads
Power only heads for both free space and fiber
optic measurements offer the capability of measuring
power only from laser diode sources while capitalizingon the wide dynamic range of semiconductor
detectors. The power measurements are madepossible by integrating sphere technology, allowing
power measurements up to 30dBm. The fiber optic
heads ensure high sensitivity, high stability, and low
noise power measurements by temperature controllingthe detectors.

Power/Waveheads
Power/Waveheads combine precision power
measurement capability with ILX Lightwave’s unique
wavelength measurement capability to deliver a costeffective laser diode measurement tool. For example,
the OMH-6732B Head with wavelength accuracy of±0.5nm eliminates the need for additional wavelength
measurements in short wavelength laser diode testing,saving time and money.
Since these heads measure wavelength, they havethe unique capability to “self calibrate” the wavelength
dependent response of the detector. There is noneed to enter a wavelength for an accurate power
measurement; the instrument does it automaticallyby sensing the wavelength. This allows the OMM-

6810B with one of the power/waveheads to act like aspectrally-flat thermal detector.

Sophisticated, Yet Simple to Operate
The OMM-6810B can be intuitively operated
from the front panel or via the standard GPIB
interface. Optical power can be read on the left
hand display in either linear or logarithmic units,
while wavelength is displayed on the right handdisplay in either nanometers or wavenumbers. Both
5-digit, green LED displays are easy to view, evenwith safety goggles on.
For optical alignment, the optical power level isalso easy to monitor on the clear, 16-segment, analog
intensity bar graph. An analog output port on the rear
panel, with a voltage proportional to power, is also
provided for remote monitoring.

Powerful GPIB Interface Makes
Remote Control and Testing Easy
The Fiber Optic Heads offer high power measurement
capability for high power pumps and fiber lasers.

For automated control, the GPIB interface allows
remote programming and instrument operationin research and development or manufacturing
environments. All instrument and measurement

head functions accessible from the front panel arealso accessible through the GPIB interface, making
data gathering quick and accurate. In addition, aLabVIEW® driver is available for download from the
ILX Lightwave website.
