Abstract
An method for producing an optical assembly includes a first assembling step of assembling lenses from a first lens to an (n−1)-th lens (where n is an integer of 1<n≦N) to a lens-holding member to assemble a pre-assembly; an optical property-measuring step of measuring optical properties of a first optical system in the pre-assembly; an optical parameter correction value-calculating step of obtaining displacement amounts from design values of the optical properties of the first optical system based on measurement results of the optical properties, and changing the optical parameters of at least the n-th lens itself from design values thereof, thereby calculating correction values of the optical parameters of the n-th lens; a lens-producing step of producing the n-th lens based on the correction values; and a second assembling step of assembling the n-th lens produced in the lens-producing step to the pre-assembly.
