    • The invention relates to an assembly for projecting an image onto a projection surface. Said assembly comprises a light source (1), which emits light and can be used to create a luminous field (3), a reflective light modulator (12; 13; 14), which can be exposed to light that exits the luminous field (3) and which modulates said light to create an image and a projection optical system (16) connected downstream of the light modulator (12; 13; 14), which can be impinged by the modulated light, to project the image onto the projection surface (17). The invention is characterised in that an optical device (7; 23; 31; 33; 34) is connected upstream of the light modulator (12; 13; 14), said device both focussing the light emanating from the luminous field (3) onto the light modulator ( 12; 13; 14) and also focussing the light modulated by the light modulator (12; 13; 14) onto an intermediate plane (ZE) located upstream of the projection optical system (16), in order to create on said plane (ZE) an intermediate image that can be projected by the projection optical system onto the projection surface.

    • A camera capable of pickup of a reduced image and a magnified image. The camera comprises a case main body (11) having a built-in CCD (15) and a lens barrel (12). A contact body (20) having a built-in objective lens (40) is arranged in the interior of the lens barrel (12) and an operation body (30) is rotatably arranged on the exterior of the lens barrel (12). The contact body (20) is moved forward and backward in the optical axis K direction by rotation of the operation body (30). A user moves the contact body (20) forward and backward so as to move the objective lens (40) forward and backward to pickup a reduced image or a magnified image. When a reduced image is picked up, the contact body (20) is contained in the lens barrel (12). When a magnified image is picked up, the contact body (20) protrudes from the lens barrel (12). The tip end position of the contact body (20) is a position whose center is matched with the focus of the objective lens (40). When a magnified image is to be picked up, a user brings the tip end of the contact body (20) into contact with an object to be picked up.

    • Projection lens systems for use with cathode ray tube (CRT) projection televisions are provided which have positive first lens units (U1) and negative second lens units (U2) where the negative second lens units are customized in terms of at least one optical property for at least two of the colors of light produced by the CRTs with which the units are used. The at least one optical property is not spectral transmission, although the second lens units can also be customized for spectral transmission. As illustrated in Figures 1B-1F and Figures 8B-8F, such customization of a non-transmissive property provides an effective and cost effective approach for improving the color performance of CRT projection lens systems. Constructions for the positive first lens unit which improve image contrast and reduce manufacturing costs are also provided.

    • The invention concerns an optical architecture for an infrared viewing system used in a pair of binoculars or a camera, comprising a front afocal lens (1), a scanner (2), an optical device (3, 3') forming an image of the scene and a cooled sensor (6) with its cool diaphragm (5). Said architecture has an aperture diaphragm separate from the cool diaphragm (5), thereby bringing about structural flux variations over the length of the sensor (6). These variations are corrected by an adapted form of the cool diaphragm (5), which smoothes and/or reduces over the length of the sensor (6) the photometric inefficacy.
