The ILX Lightwave OMH-6722B is a silicon-based power and wavelength measurement head delivering simultaneous optical power and wavelength characterization across the visible and near-infrared spectrum. Built around an integrating sphere design, it provides measurements insensitive to beam profile, alignment, polarization, and back reflection—critical advantages for reliable laser source characterization. The head operates with the OMM-6810B Optical Power and Wavelength Meter or the LWM-6500B Laser Wavelength Meter, with all calibration traceable to NIST standards.
