The ILX Lightwave OMH-6790B is a silicon-based power and wavelength measurement head engineered for integration with the OMM-6810B Optical Multimeter. This unit delivers simultaneous optical power and wavelength measurement across the 830 to 1100 nm band, supporting dynamic ranges from 1 µW to 10 W. The measurement head accommodates fiber sizes from 9/125 µm to 110/140 µm with NA = 0.3, and features a 2.54 mm fiber input port. A fiber tap is included for spectral characterization of high-power sources via optical spectrum analyzer connection.
