Power and Wavelength Meter, 120 VAC

The OMM-6810B-120V is the only power meter capable of measuring the optical power and wavelength of semiconductor lasers including short wavelength lasers, high power pumps, and fiber lasers. A variety of measurement heads cover wavelength ranges from 400 to 1650 nm for power only or power and wavelength measurement.  This version is designed for a 120 VAC power source.

Wide Variety of Measurement Heads

The OMM-6810B Optical Multimeter coupled with the OMH-6700B Series Optical Measurement Heads, provide the flexibility to easily and accurately measure the optical power of short wavelength lasers, higher power pump, and fiber laser diodes.

• Power only heads offer the capability of measuring power only from laser diode sources while capitalizing on the wide dynamic range of semiconductor detectors. The fiber optic heads ensure high sensitivity, high stability, and low noise power measurements by temperature controlling the detectors.
• Power and Wavelength heads on the other hand, have the unique capability to "self-calibrate" the wavelength dependent response of the detector. This allows the OMM 6810B with one of the power/waveheads to act like a spectrally flat thermal detector.
• Measurement Head are Required and Sold Separately

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 hand display in either nanometers or wavenumbers. Both 5-digit, green LED displays are easy to view, even with safety goggles on. For optical alignment, the optical power level is also 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

Count on High Performance

The OMM-6810B is an accurate, low noise power meter capable of measuring optical power over an 80dB dynamic range and offers the stability and repeatability necessary for precise power measurement. Packed with other features including a simple wavelength measurement technique developed at ILX Lightwave, the OMM-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 measurement with wavelength measurement accuracies from several tenths of a nanometer to one nanometer. For spectral measurements of high power sources, a fiber tap is included on the OMH-6790B Power/Wavehead to allow convenient connection to an optical spectrum analyzer.

Ideal For Laser Diode Testing Applications

Power & Wavelength heads combine precision power measurement with ILX’s unique power and wavelength capability, based on integrating sphere technology, to deliver a cost-effective laser diode measurement tool. The integrating sphere measurement method simplifies optical power measurements of laser diodes and LEDs by eliminating measurement problems related to detector saturation, alignment beam profile, polarization, and back reflection. Since these heads measure wavelength, they have the unique capability to "self-calibrate" the wavelength dependent response of the detector. There is no need to enter a wavelength for an accurate power measurement; the instrument does it automatically by sensing the wavelength. This allows the OMM 6810B with one of the power/waveheads to act like a spectrally flat thermal detector.

In addition to precision power and wavelength measurements, the OMM-6810B is loaded with standard features such as log/linear display modes, auto ranging, user calibration, and reference measurement capability. All of these features plus an analog output and IEEE-standard GPIB interface combine to make this instrument a cost-effective laser diode development or production test tool.
