ILX Lightwave OMH-6722

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 has 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.
