Abstract: A display apparatus has an image generator that generates image-bearing light from a f surface and a lens spaced apart from the image generator and having an aspheric incident refractive surface concave to the image generator and having an aspheric reflective surface concave to the image generator, wherein a principal axis of the reflective surface is normal to the image generator. A beam splitter plate disposed in free space between the image generator and the lens has first and second parallel surfaces that are oblique to a line of sight of a viewer. The lens and the beam splitter plate define a viewer eye box for the image-bearing light along the line of sight of the viewer.

Abstract: An optical system includes a lens assembly and a light source. The lens assembly includes an optical lens positioned to transmit and refract light provided by the light source, and a lens holder coupled to the optical lens and maintaining a position of the optical lens relative to the light source. The optical lens is coupled to the lens holder with a bonding agent arranged in an interrupted configuration at positions proximate to a circumference of the optical lens. The light source provides light to the optical lens of the lens assembly that has an optical footprint that includes a plurality of high-intensity regions separated from one another by low-intensity regions and the bonding agent is positioned in a circumferential orientation relative to the light source such that the bonding agent is spaced apart from the high-intensity regions of the optical footprint of the light.
