Aberrational Astigmatism

Calculation from Diepes/Blendowske "Optik und Technik der Brille".
A negative ΔS' could be compensated by the eye if ΔAmax is sufficient.

Parameter

r1 = mm
r2 = mm
d = mm
Ø = mm
n = 1,525 1,67 1,74 1,8
s0 = mm - ∞ - 38 cm
HSA = mm standard
Material glas plastic

Glas Calculation

S'F' = dpt D1 = dpt D2 = dpt
