4.2.2.14 Set wavelength

The calibration data of phase level can be adjusted with a user specified wavelength.

The arbitral wavelength within 450nm to 1600nm can be set at a 1 nm interval.
If 

“No wavelength calibration “ is selected, the phase level is adjusted for 1550nm.   

Maximum optical phase at specified wavelength can be adjusted to the inputted value in 

“Optical phase change”. The setting change takes about 30 to 40 second.
