Abstract
A fixture apparatus for positioning an optical component has a transparent base. An adjustment plate that is formed from a transparent material is kinematically coupled to the base. Support posts extend from the adjustment plate for seating the optical component. A number of alignment elements extend from the transparent base for aligning one or more edges of the optical component seated on the support posts.
Claims17
A fixture apparatus for positioning an optical component, the apparatus comprising:
- a transparent base having opposing top and bottom surfaces;
- an adjustment plate, having opposing top and bottom surfaces, that is formed from a transparent material and is kinematically coupled to the base such that the bottom surface of the adjustment plate faces the top surface of the base;
- a plurality of support posts that extend from the top surface of the adjustment plate for seating the optical component;
- a plurality of alignment elements that extend from the top surface of the transparent base for aligning one or more edges of the optical component by contacting the optical component seated on the support posts;
- and
- a spring that directs a loading force against the adjustment plate.
A fixture apparatus for positioning an optical component, the apparatus comprising:
- a transparent base having opposing top and bottom surfaces;
- an adjustment plate, having opposing top and bottom surfaces, that is formed from a transparent material and is kinematically coupled to the base by first, second, and third adjustable supporting elements that extend from the base such that the bottom surface of the adjustment plate faces the top surface of the base;
- first, second, and third support posts that extend from the top surface of the adjustment plate for seating the optical component;
- first, second, and third edge alignment elements that extend from the top surface of the transparent base for aligning one or more edges of the optical component by contacting the optical component;
- and
- a spring that directs a loading force against the adjustment plate.
