Patent ID: 8053711

Claim:
An apparatus for controlling spherical aberration in an imaging system comprising: a plurality of objective lenses, wherein at least one of the plurality of objective lenses has a spherical aberration collar; the plurality of objective lenses mounted onto a objective holder, wherein the objective holder is configured to place the at least one of the plurality of objective lenses in an imaging position; a plurality of driving mechanisms, wherein at least one of the plurality of driving mechanisms is coupled by a mechanical link to the at least one of the plurality of objective lenses, wherein the mechanical link is configured to transmit motion from at least one of the plurality of driving mechanisms to the spherical aberration collar of the at least one of the plurality of objective lenses; and a plurality of driving mechanism controllers, wherein at least one of the plurality of driving mechanism controllers is configured to manipulate at least one of the plurality of driving mechanisms to move the spherical aberration collar of the at least one of the plurality of objective lenses in the imaging position to a specific spherical aberration adjustment setting.
