The Newport / ILX Lightwave OMM-6810B Optical Multimeter simultaneously measures optical power and wavelength in laser diode and fiber optic systems. This dual-function instrument integrates power meter and wavelength meter capabilities into a single platform, delivering 80 dB dynamic range power measurements and wavelength accuracy to ±0.2 nm with compatible Power/Waveheads. Measurement head flexibility spans multiple detector types—Power/Waveheads with integrating sphere technology, Power-only heads for semiconductor laser sources, and temperature-controlled fiber optic heads—each configured for FC, LC, ST, SC, bare fiber, or Ericsson bare fiber clip connectors. The instrument operates via front panel controls or IEEE-488.1 (GPIB) interface for automated test system integration. Dual 5-digit green LED displays present power in linear (pW, nW, µW, mW, W) or logarithmic (dB, dBm) units, with 0.001 unit resolution. Power/Waveheads employ integrating sphere architecture, enabling self-calibration of wavelength-dependent detector response and functioning as spectrally flat thermal detectors. This design eliminates sensitivity to detector saturation, alignment variance, beam profile, polarization, and back reflection effects—critical for demanding metrology in telecommunications, research, and manufacturing environments.
