Appl. No.:

09/616130

Inventors:

Robert E. Fischer - Westlake Village CA
Michael P. Newell - Thousand Oaks CA

Assignee:

Optics 1, Inc. - Westlake Village CA

International Classification:

G02B 1318

US Classification:

359708, 359569, 359643, 359802

Abstract:

A lens design form is used for a viewing optical system or magnifier that includes a cemented doublet and a weak aspheric element, for example, made of acrylic, and having a diffractive kinoform surface superimposed on the surface profile of the aspheric element. The design significantly reduces both chromatic aberrations and minimizes most of the monochromatic aberrations of the optical system or magnifier. By allowing the lens design form to produce an image on a curved surface, optical performance is improved further over the prior art systems because this allows the elements in the system to control the image blurring aberrations rather than having to also control field curvature. The human eye can accommodate for the curved field, and thus the curved field does not reduce image quality, but instead allows image quality to be enhanced. The viewing optical system also can be used for image projection.

International Classification:

G02B 300

US Classification:

359649, 359618, 359663

Abstract:

Projection lenses and projection lens systems are telecentric between an illumination subsystem and a set of imagers. The lenses and systems can exhibit color fringing correction, uniform imager illumination, athermalization, and component articulation for improved imaging. The lenses and systems may be employed in display apparatuses, such as folded display apparatuses that have decreased footprint size, but long effective projection lengths.

International Classification:

G01B 900

US Classification:

356124

Abstract:

A method and system for inspecting ophthalmic lenses using absorption where an ophthalmic lens is illuminated with light comprising wavelengths that are substantially absorptive to said lens, the image subsequently detected being created using only light at said absorptive wavelengths. Variations in transmitted light intensity translate into thickness changes in the lens caused by cosmetic flaws. The invention is also directed to imaging lens assemblies employing highly positive-powered field flattening lens elements to image a curved object, such as an ophthalmic lens, onto a flat image plane.

International Classification:

US Classification:

359 15, 359 13, 359599, 362558

Abstract:

Systems and methods for providing illumination suitable for imaging devices such as laser projection systems. In one embodiment, a highly collimated (e. g. , laser light) beam is passed through a holographic diffuser to create a well defined cone angle for the light emanating from each point on the diffuser. This light is focused into an illumination image that is controlled by the prescription of the diffuser. In one embodiment, the image is a uniformly intense rectangle having a 4:3 aspect ratio to match an imager for a projection display. The diffuser prescription and resulting illumination image can be selected to match any desired imager. The present systems and methods may provide the advantages of high level of light efficiency, reduction or elimination of speckle and worminess and reduction or elimination of cosine and gaussian intensity falloff, all of which are common in prior art designs.

Abstract:

A flashlight that generates a flashlight beam to illuminate an object at a selectable distance from the flashlight by imaging a uniformly bright pattern of light onto the object. A light modifying component can be used to manipulate the pattern of light into particular shapes and images. In one embodiment, light from a light source is coupled into a light pipe. The light is homogenized as it travels along the light pipe. The light exits the light pipe with a more uniform intensity than when it entered. The light exiting the light pipe is then reimaged by an imaging lens onto an object. Yet in other embodiments, one or more lens arrays having two or more lenlets are used to homogenize the light originating from the light source.
