The ILX Lightwave OMH-6732B is a dual-function optical measurement head that combines power and wavelength measurement into a single probe for laser diode and LED characterization. Silicon detectors integrated with an integrating sphere architecture eliminate common measurement obstacles—detector saturation, beam alignment sensitivity, profile variations, polarization effects, and back reflections—delivering repeatable, accurate results across a wide dynamic range. The head self-calibrates wavelength-dependent detector response, temperature-stabilized detectors ensure environmental independence, and all measurements trace to NIST standards.
