Calculates Bath astigmatism coefficients with optional rotation of phi degrees.
astig.bath(D, rc, s, lambda = 632.8, phi = 0)
D |
Diameter |
rc |
Radius of curvature |
s |
separation of reference and test beams |
lambda |
Wavelength |
phi |
angle of image horizontal relative to interferometer axis, in degrees |
D, rc, s, must have the same units. If those units are mm the source wavelength lambda should be in nm.
The Zernike coefficients for primary astigmatism terms.
