in which dpi is a function of y. This gives from (3.233) if n = 1 for a glass plate in air:

32fi3 2fi2'

where (dpi)o is the axial thickness of the plate. Following Bahner [3.5], we now define a dimensionless profile constant kpi in units of the Az0 focus shift defined by (3.234) as

ym together with the normalized height ppi as

Eq. (3.237) can now be written
