Abstract:
An optical device, comprising:a fixed reference mount having a first registration feature and a second registration feature; a first optical module 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 including a registration feature having a three dimensional shape configured to align with the first registration feature of the fixed reference mount wherein the alignment between the relative reference mount and the fixed reference mount is repeatable in six degrees of freedom on the fixed reference mount, the optical component held at a prealigned spacial orientation relative to the registration feature 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; and a second optical module, 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; and a relative reference mount including a registration feature having a three dimensional shape configured to align with the second registration feature of the fixed reference mount wherein the alignment between the relative reference mount and the fixed reference mount is repeatable in six degrees of freedom on the fixed reference mount, the optical component held at a prealigned spacial orientation relative to the registration feature 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.
