    摘要: An apparatus for collimating or focusing a coherent light beam without beam misalignment or beam focal point drift due to thermal deformation. The apparatus includes an optical component made of a material having an optical coefficient of thermal expansion and an optomechanical component having an optical support configured to hold the optical component. The optical support is made of a material having an optomechanical coefficient of thermal expansion, wherein the optical coefficient of thermal expansion and the optomechanical coefficient of thermal expansion are selected such that the optical component and the optomechanical component expand or contract as a single entity under varying temperatures.

    摘要: A dynamic concentrator system having a concentrator lens, a tracker platform and a receiver. In an embodiment, the concentrator lens is configured to receive an incoming light at an entrance angle α and concentrate the light beam on a focus spot. The tracker platform has a detector optical aperture and one or more actuators. The detector optical aperture can be configured to receive the concentrated light beam. The actuators can move the detector optical aperture in a spatial plane to a location of the focus spot. The receiver has a detector optically coupled to the detector optical aperture to receive the concentrated light beam from the detector optical aperture.

    摘要: A light source device which is miniaturized, can be manufactured at low cost, and is suitable as an illumination light source of a display device of an electronic device such as an HUD and an aerial floating image display apparatus is provided. The light source device includes: a light source configured to generate white light by irradiating a phosphor with light emitted from a solid-state light source; a collimating optical system (15) configured to convert a divergent light flux of the white light emitted from the light source into parallel light; a light guide configured to cause the light emitted from the collimating optical system (15) to be incident as incident light and emit the incident light in a direction different from an incident direction; and a filter configured to reflect light in a blue region of the parallel light to irradiate the phosphor.

    摘要: 1. A medical light (100) has an illumination unit (10) having lighting means (20) and optical means (30) for generating a light field (200), wherein the lighting means (20) are formed by an essentially punctiform LED light source (21) and the optical means (30) have a plate-shaped collimator (40) and a cover pane (50). The collimator (40) has a central area (42), which is provided with light-refracting structures (43) on a side facing away from the LED light source (21), and an outer area (46), which is provided with structures (48) designed for total reflection on a side facing toward the LED light source (21), wherein the cover pane (50) is provided with a lens structure, which has a plurality of individual lenses which each project the light emitted by the collimator (40) onto the object plane. The rear side of the central area of the collimator facing toward the LED light source is provided with partial surfaces (45, 145), which have an inclination in relation to a plane (E3) of the collimator (40), in order to asymmetrically expand the light field (200) in one direction.

    摘要: A multi-spot ophthalmic laser device that produces spatially distributed laser spots with the spatial distribution of the laser spots defined by a spot diameter to space ratio in the range 1:2 to 1:20. The multi-spot ophthalmic laser device comprises: a laser module producing a laser pulse or sequence of laser pulses each having: a pulse duration in the range of 10 ps to 20 μs; a wavelength in the range 500 nm to 900 nm; and a pulse energy in the range 10 μJ to 10 mJ per pulse; and an optical beam profiling module that modifies an output beam profile of each pulse of the laser module to deliver multiple spatially distributed laser spots of defined size and energy. The multi-spot ophthalmic laser device is used in a method of improving the function of the retina of a human eye by irradiation through the cornea of the eye to the retinal pigmented epithelium by a treatment laser having a beam profile with spatially distributed energy peaks.
