Abstract
Aspects of the present invention relate to providing see-through computer display with improved optics.
Claims7
A method for manufacturing a solid prism with a flat reflecting surface for a head-worn display comprising:
- a. molding a solid prism of an optical material with one or more optically powered surfaces and at least one planar surface;
- b. after molding, applying a drop of transparent UV curing adhesive with a refractive index that is index matched to the optical material of the flat surface;
- c. applying a flat reflective plate to the drop of adhesive;
- d. allowing the adhesive to wick across an interface between the planar surface and the flat reflective plate without applying pressure to the flat reflective plate to avoid distorting the flat reflective plate, until the entire interface is covered by adhesive;
- and
- e. applying UV light to the interface to cure the adhesive and form a solid prism with a flat reflective surface.
