Abstract:
An optical module for use in an optical device, comprising:an optical component having an optical characteristic which varies based upon a position of the optical component in space relative to at least one dimension and wherein component variability causes a variability in the optical characteristic; a relative reference mount having a registration feature with a three dimensional shape configured to constrain movement in six degrees of freedom when physically coupled to a corresponding registration feature of a fixed reference mount and to provide a repeatable is registration therebetween; an adjustable optical component mount configured to fixedly couple to the optical component and have an adjustable position relative to the relative reference mount; and a bond configured to bond the optical component mount to the relative reference mount and thereby fix the optical component relative to the registration feature of the relative reference mount at a prealigned position relative to the registration feature of the relative reference mount to adjust for the variability in the optical characteristic of the optical component prior to placing the relative reference mount in the fixed reference mount whereby the optical component is fixed in six degrees of freedom relative to the registration feature of the relative reference mount.
