Product Features
Measures optical power from400 to 1600nm
NIST traceable calibration
Integrating sphere-based
measurements
Free-space and fiber-coupledmeasurements

The OMH-6700B Power Only Measurement Heads
provide the flexibility to easily and accurately measure theoptical power of laser sources from 400 nm to 1600nm.
These products are integrating, sphere-based power
measurement heads for either free-space or fiber coupledmeasurements. The OMH-6703B Silicon Power Headmeasures from 400 to 1000nm while the OMH-6708B uses
an InGaAs detector to measure from 800 to 1600nm.
The OMH-6703B and the OMH-6708B are intended foruse with the ILX Lightwave OMM-6810B power meter. Withthe 6703B and 6708B, the OMM-6810B measures the opticalpower of short and long wavelength semiconductor lasers.
In addition to precision power measurements, the OMM6810B offers features such as log/linear display modes,
auto ranging, user calibration, and reference measurement
capability. With an IEEE standard GPIB interface, thesefeatures combine to make this instrument a cost-effective
laser diode development or production test tool.

Simplify Optical Measurements
Integrating spheres simplify optical power
measurements of laser diodes and LEDs byeliminating measurement problems related to detector
saturation, alignment beam profile, polarization, andback reflection. Integrating spheres are inherently
insensitive to beam profiles, providing you withmore flexibiity in laser type and launch conditions.
Detectors on the interior of the sphere receive anequal distribution of incident light, ensuring thecalibration and resultant measurement accuracy areindependent of the beam profile.

Measure with Confidence
The OMH-6700B Power Only Measurement
Heads are calibrated to NIST traceable standards
in ILX’s own calibration laboratory, where accuracy

and traceability are its primary concerns. ILX’s
documented quality system ensures conformance tocontinuous traceability and ultimately your confidence
in the power measurements.

Measurement Flexibility
Each measurement head can be configured
for free-space or fiber-coupled measurements. A
choice of adapters for fiber coupled measurements isavailable for FC, SC, ST, and DIN connectors. Bare
fiber measurements are also possible with a bare fiber
adapter. Configuration of the measurement heads
with the desired adapter is simple.
Each head can be ordered with a head mounting
kit that comes with an adjustable mounting post so
the head integrates easily into your measurement
setup.

Typical values provide supplemental information beyond guaranteed specificationlimits.
1. Unless otherwise noted, all specifications measured at 23oC +3oC after one
hour warm up period. Fiber optic head specifications applicable for 9/125 to
110/140µm fiber, NA = 0.3.
2. Minimum sensitivity -40dBm from 800 to 1100nm.
3. Includes traceability to NIST. Calibrated to 21oC +3oC at 10nm intervals.
Uncertainty evaluated according to NIST Technical Note #1297: “Guidelinesfor Evaluating and Expressing the Uncertainty of NIST Measurement
Results.” Accuracy specification are verified with the wavelength enteredmanually (instrument not in auto-wavelength mode).
4. Add +0.5% for <440nm and >1000nm.
5. Measured over one minute, in gain range seven, medium filter mode.
6. At 980nm.
