User Manual
Selects for each wavelength, the backscatter coeffi-
cient of -99 dB to -50 dB by increments of 0.1dB.
Modification of the backscatter coefficient K changes
the measurements of reflectance and ORL.
Backscatter coefficients are selected automatically for
each wavelength.
Generic 50: 850 MM - > -66.3 dB
1300 MM -> -73.7 dB
Generic 62.5: 850 MM -> -66.1 dB
