finesse.thermal.hello_vinet.surface_deformation_substrate_heating(data, h)

Computes the depth displacement change of the surface of an optic due to bulk absorption from a generic axisymmetric heating profile. Displacement returned is in units of m per absorbed Watts through entire substrate.

The accuracy of this computation decreases as h/a > 1. The substrate modelled must be disk like. The error is more pronounced towards the edge of the substrate.

Parameters:

datatuple

Irradiance fit data from get_p_n_s_numerical()

hfloat

mirror thickness

Returns:

U_z_bulk_per_Wndarray(shape=(r.size.))

Array of z displacements per watt of absorbed power through entire substrate [1W/h]

Notes

Solving equation 3.165 [27]

Currently only works for n_max == 0.
