摘要： A color cathode ray tube of the shadow mask or beam index type in which the screen structure applied to the faceplate has a plurality of triplets of optical interference filter stripes which are adapted to pass red (R), green (G) and blue (B) light produced by a homogeneous cathodoluminescent screen layer. The usual aluminium layer may be applied to the screen layer. The optical interference filter stripes may have short wave pass filters, band pass filters or a combination of both types. The short wave pass filter stripes may have modified quarter wavelength multilayer dielectric filters and the bandpass filter may have a Fabry-Perot filter.

摘要： Projection television display device includes three monochrome projection television display tubes (20, 21, 22) each having a display screen (24, 25, 26) which is provided on the inside of the display window (23) and luminesces in a different color. Each tube has an optical axis extending perpendicularly from the center of the display screen, the optical axes (33, 34, 35) of the three display screens being co-planar. The axes (34, 33) of the display screens of the first and second tubes (20, 22) coincide and the axis (35) of the display window of the third tube (21) constitutes the main axis of the device, the axis being perpendicular to the two coincident axes (33, 34). Two flat dichroic intersecting reflective mirrors (27, 29) extend perpendicularly of the plane and through the point of intersection of the axes, each at an angle of 45.degree. with the main axis. The first mirror (27) reflects the image of the first display screen and the second mirror (29) reflects the image of the second display screen into the direction of the main axis and away from the third display screen, interference filters being disposed between the display screens and mirrors for passing the desired color of light. With interference filters disposed between the luminescent material of the display screens and the display windows, the reflection greatly increases for light rays constituting an angle of more than 20.degree. to 35.degree. with the normal of the filter. When there is substantially no transmission up to 90.degree., there is a gain in brightness by a factor of 1.5 to 2, a gain in contrast by more than a factor of 2 and also a considerable color improvement and reduction of color errors when the conventional green and blue phosphors are used.

摘要： In an interferometer system, variations of the refractive index in the medium traversed by the measuring beam (123) can be detected by using two measuring beams (123, 125) having wavelengths which differ by a factor of three. For this choice of the wavelength ratio, the interference filters of the polarization elements, such as the beam splitter (127), the .lambda./4 plates (130, 131) and the antireflection coatings can be manufactured relatively easily, and the detection accuracy is increased.

摘要： A rewritable single-sided double layer optical information medium having a first recording stack with a phase change recording layer sandwiched between two dielectric layers. The recording stack is sufficiently transmissive to ensure proper reading/writing of the second recording stack. For this purpose, the recording stack includes a thin metal layer and a further dielectric layer. The laser beam can be focused on the first recording stack or on the second recording stack, thus doubling the storage capacity of the recording medium.

摘要： The invention relates to a method of manufacturing a radiation-emitting semiconductor diode (10) whereby a sacrificial layer (1) comprising a polymer is provided on a first side face (11) of a semiconductor body (20) which contains at least one radiation-emitting semiconductor diode (10), a coating (2) is subsequently provided on the first side face (11) and on a second side face (12) of the semiconductor body (20) which encloses an angle with the first side face (11) and which forms an exit face for the radiation to be generated by the diode (10), after which the first side face (11) is divested of the sacrificial layer (1) and of the portion (21) of the coating (2) situated thereon through etching of the sacrificial layer (1). It is possible by such a method, for example, to cover the mirror faces (11, 14) of a laser diode (10) selectively with a reflecting, anti-reflection, or passivating coating (2). A disadvantage of the known method is that laser diodes (10) manufactured thereby are difficult to solder. According to the invention, this disadvantage is obviated in that a protective layer (3) comprising an inorganic material is provided on the sacrificial layer (1) before the provision of the coating (2) in the method. Such a protective layer (3) prevents damage to the sacrificial layer (1), and thus prevents portions of the coating (2), which cannot be removed anymore, from depositing on the first side face (11) which comprises, for example, a metal layer (7). Preferably, the protective layer (3) comprises a metal, for example aluminium. This also prevents the sacrificial layer (1) from becoming badly soluble owing to UV radiation released in a sputter deposition process of the coating (2). Remainders of the sacrificial layer (1) on the metal layer (7), which also result in bad soldering properties, are avoided thereby. (Laser) diodes thus manufactured have a long useful life and are highly suitable for high-power applications.

摘要： An anti-reflection coating which comprises at least a three layer interference filter is evaporated on the external surface of a faceplate panel. The manufacture of the coating can be speeded-up substantially by selecting high and low refractive index materials which can be evaporated at ambient temperatures and subsequently hardened by high temperature annealing outside the evaporation apparatus. The annealing is carried out most conveniently during the standard processing of a cathode ray tube.
