Hello,
I wanted to get the wavefront map of a cerain zernike coefficient representing an aberration. Is there a way to change the unit ‘WAVES’ into ‘mm’ or ‘nm’?
Hello,

The wavefront map is always given in waves.
Could you help me with this unit ‘Waves’ then as I don’t fully understand it? To be able to convert it to ‘mm’ for example, can I multiply it by the waelength of the source?
Hi
The wavefront map shows optical path differences between rays of a field and the chief ray of that same field at a given wavelength.
The path is measured with a unit of length, like mm and then converts to waves.
If your wavelength is for example 0.55um, then the conversion will be:
wave = 0.55um = 0.00055 mm
OPD in wave = OPD in mm / (0.00055 mm)
