The pair of conjugate points where the spherical aberration is zero and the sine
condition is kept valid are known as aplanatic points of the surface Q. If the object
(and the front aplanatic point) is located at infinity the sine condition is ...

are inappropriate. When an achromatic doublet is used, the extra degree of

The Crust and Upper Mantle of the Pacific Area
In brief, the method of aplanatic surfaces is applicable where the shot point and
the geophone are in two different media, and it is preferable that the geophone
be in the high velocity medium. It is assumed that no other medium exists
between ...
