摘要： The present invention provides variable spot size illuminators that provide a light spot on a treatment plane by utilizing a zoom lens to direct light received from an image of a light source formed on an intermediate image plane onto the treatment plane. The zoom lens allows varying the size of the treatment spot while ensuring that the treatment spot exhibits parfocality. An illuminator of the invention can be utilized for performing a number of ophthalmic surgical procedures, such as, photocoagulation, transpupillary thermal therapy, and photodynamic therapy.

摘要： 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 cosine4 and gaussian intensity falloff, all of which are common in prior art designs.

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.

摘要： A compact work light that generates a light beam having high brightness and high illumination uniformity is disclosed. The work light includes a housing that houses a light source, a light homogenizer and an imaging lens in an operational relationship. The housing is attached to an adjustable mount, which can be attached to a fixed region such as wall, or to a movable support member such as a lamp base. The light source generates light that is uniformized by the light homogenizer. The homogenized light is then imaged by the imaging lens as a highly uniform, bright beam spot having a sharp boundary. The beam spot is formed at a selectable distance from the work light by varying the imaging lens and/or the adjustable mount. The work light is useful for a variety of industrial, professional and personal applications, including but not limited to a reading light, a dentist light, a head lamp, a head light and an optical projector.

摘要： 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.

摘要： 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.

摘要： Modified MZ (Mach-Zender) interferometers are utilized to analyze the transmitted, aspherical wavefront of an ophthalmic lens by mounting the lens in a cuvette having a rotatable carousel that can hold multiple lenses. Fresh, temperature controlled, saline solution is circulated about the lenses, and the cuvette is positioned in a vertical test arm of the interferometer configuration. Reverse raytracing is utilized to remove aberrations induced into the wavefront as it is imaged from immediately behind the lens to the detector of the interferometer.

摘要： A flashlight that utilizes an array of one or more light-emitting diodes (LEDs) as a light source, and a light pipe as a light homogenizer to generate a light beam capable of forming a uniformized light distribution at a given distance from the flashlight is disclosed. The LEDs may be all the same color, or some or all may be different colors. A switch, coupled to switching electronics coupled to the LED array, is used to change the state of the LED array to create a variety of different types of light beams, each of which provides relatively uniform and bright illumination at a given distance from the flashlight, wherein the given distance is selectable by adjusting an adjustable imaging lens.
