4. Light Output
Spectral distribution and power measurements are measured at the distal end of the Nikon–supplied fiber bundle.
Guaranteed minimum output A power values are given in the adjacent table along with an output spectrum
measured from one of the first production light engines (Figure 5). The two peaks in the red output band have an
intensity ratio of 0.7 or more relative to the intensity of the stronger peak normalized to a value of 1.0.
