Abstract
A method of fabricating an objective lens includes the steps of attaching a first lens to a first holder, adjusting an angle between the optical axis of the first lens and the optical axis of a second lens while sliding the second lens on a sphere, and attaching the second lens to a second holder so that the angle becomes 0°, forming contact between first and second planes, sliding the second holder with respect to the first holder in a state where the first and second planes are in contact so that the optical axis of the first lens matches the optical axis of the second lens to carry out decentration adjustment, and fixing the second holder subjected to decentration adjustment with respect to the first holder.
