Abstract
A lens aligning device includes: a decentering detection mechanism for measuring a first lens decentering amount; a aligning position calculation control mechanism for calculating a target inter-lens decentering amount by using Formula (1); an adjustment mechanism for moving at least one of a first lens and a second lens so that the inter-lens decentering amount matches the target inter-lens decentering amount.Inter-lens decentering amount=First lens decentering amount×−2 (1)
