Abstract:
The invention relates to a microscope having an illumination beam path with wide field illumination of a sample and a first detection beam path having a spatially resolved surface receiver, which is reached by a first part of the detection light coming from the sample via the first detection beam path, or an image divider assembly for a microscope. In order to lengthen the optical path length, at least a second part of the detection light coming from the sample is masked out of the detection beam path and, via deflection means belonging to the detection beam path, is led into a second detection beam path and, preferably via further deflection means, is deflected back in the direction of the detection in such a way that detection light is applied to at least two partial regions beside one another on the surface receiver. At least the second part of the detection light runs in an optical element having an optical density that is increased as compared with the first detection beam path, in order to lengthen the optical path length, and the optical element is designed to be displaceable at an angle, preferably perpendicular, to the optical axis of the first detection beam path in order to adjust the optical path length, and has flat surfaces, at least on the light entry and light exit side thereof; a prism is provided, preferably a glass prism, preferably at least in the second detection beam path after a first beam deflection, for deflection in a direction parallel to the first detection beam path, in order to increase the path length and for reverse deflection.

Abstract:
An optical device, including a light waves-transmitting substrate has two major surfaces and edges, optical means for coupling light into the substrate by total internal reflection, and a plurality of partially reflecting surfaces (22a, 22b) carried by the substrate. The partially reflecting surfaces (22a, 22b) are parallel to each other and are not parallel to any of the edges of the substrate, one or more of the partially reflecting surfaces (22a, 22b) being an anisotropic surface. The optical device has dual operational modes in see-through configuration. In a first mode, light waves are projected from a display source through the substrate to an eye of a viewer. In a second mode, the display source is shut off and only an external scene is viewable through the substrate.

Abstract:
An eyepiece for a head wearable display includes a light guide component for guiding display light received at a peripheral location offset from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The light guide component includes an eye-ward facing surface, a world facing surface, and a recess disposed in the world facing surface in the viewing region. The recess has a recessed surface that is discontinuous with the world facing surface. An add-on component is disposed in the recess and has a first surface mated to the recessed surface and a second surface that forms a continuous outer surface with the world facing surface. A partially reflective layer is disposed along an interface between the recessed surface and the first surface of the add-on component.
Abstract:
An image display device includes a transparent plate which may be disposed in an inclined manner with respect to a display section of a portable terminal provided with the display section. A display displayed on the display section may be reflected on the transparent plate. A space behind the transparent plate may be viewed through the transparent plate and, at the same time, an image on the display section of the portable terminal may also be viewed while being reflected on the transparent plate.

Abstract:
An optical rotating device for injecting a laser beam may include deflection devices between which the injected laser beam may rotate in the optical rotating device, and an extraction device that may extract the laser beam after carrying out a predetermined number of rotations in the rotating device. The deflection devices may be arranged such that the position of the laser beam during extraction is dependent on the number of rotations carried out in the optical rotating device.
Abstract:
A system and method of making a remarkably bright high-gain reflective beam-splitter is presented. Each non-glued together touching layer of the multilayered film of the beam splitter has front and back reflective surfaces that additively increase the brightness. The system can include tables, step-down shelves, cutting bars, gripper units, tension units, a frame, a hoist assembly, and dollies. Constructing the beam-splitter can use grippers that slip slightly, as a function of applied tensioning force, along the trimmed edges of the multilayered film. This slip gripping scheme can result in constructing substantially coplanar sheets of the multilayered film that touch each other face to face and result in removing most of the air between the sheets. The planar integrity of the multilayered film of the high-gain reflective beam-splitter can be maintained at almost any desired display angle even when the high-gain reflective beam-splitter is as large as a standard theatrical stage.
