The invention relates to a method for quantitative determination of test results from diagnosis methods with the aid of an optoelectronic evaluation appliance, and to the evaluation appliance itself, characterized in that the digital pixel information per color level or grey level is represented in its intensity in the microprocessor as one column per pixel, wherein the column height corresponds to the intensity, and these columns are displayed alongside one another on one plane, such that the intensity distribution is displayed over the test area as a surface contour or surface profile, the height profile of which corresponds to the intensity profile of the color intensity received by the CCD. Fields of application for the invention are test methods in biochemical laboratories, such as medical diagnosis, forensic medicine, foodstuff diagnosis, molecular biology, biochemistry, gene technology and all other related fields, as well as patient monitoring for home users or in pharmacies.

Appliance and method for evaluation and assessment of a test strip

The invention relates to an optoelectronic transmission and/or reception arrangement. The arrangement includes a transmission and/or reception module containing an optoelectronic transmission and/or reception component, and a plug interface for the coupling of an optical fiber thereto. An optical waveguide section is arranged in the plug interface, and at one of its ends is optically coupled to the transmission and/or reception component. At its other end, the optical waveguide section is configured to be coupled to an optical fiber. The arrangement may further include a lens for optical coupling of the light between the optical waveguide section and the transmission and/or reception component. The lens and the optical waveguide section, in one example, are formed as a prefabricated subassembly, in which the lens is fixedly arranged at a defined distance from one end face of the optical waveguide section.

Optoelectronic transmission and/or reception arrangement

The optical fiber holder of the coupling device has a top, a bottom, and narrow side faces between the top and the bottom. Intermediate faces are formed at the transitions between the narrow side faces and the top and the bottom. A receptacle into which the holder is inserted axially has internal contact areas which are in contact with the intermediate faces without play.

Coupling device

A configuration for coupling optical signals of at least one optical data channel into and/or out of an optical waveguide carrying optical signals of at least two optical data channels includes at least two optical waveguide sections forming the optical waveguide, the sections positioned axially one behind the other, at least core regions of two optical waveguide sections being positioned one behind the other separated from one another by a free-radiating region, an end face of at least one waveguide section running obliquely with respect to an optical axis () of the waveguide and being coated with a wavelength-selective filter, and, for a specific optical data channel, light being coupled into or out of the optical waveguide by reflecting light of the optical data channel, before or after traversing the free-radiating region, at the end face of the optical waveguide section running obliquely with respect to the optical axis.

An arrangement including an optoelectronic component having terminal contacts, an electrical component having first electrical contacts and second electrical contacts, a printed circuit board, to which the second electrical contacts of the electrical component are connected, and a flexible conductor arrangement of a planar form having several conductor tracks. The conductor arrangement provides an electrical connection between the terminal contacts of the optoelectronic component and the first electrical contacts of the electrical component. The conductor arrangement has a first region with first contact regions and a second region with second contact regions. The optoelectronic component is mounted directly on the first region and its terminal contacts are connected to the first contact regions, and/or the electrical component is mounted directly on the second region and its first electrical contacts are connected to the second contact regions.

Arrangement for the electrical connection of an optoelectronic component to an electrical component

A coupling configuration enables the coupling of an optical plug with a plug pin to a mounting tubelet wherein at least one optical conductor is arranged in at least one ferrule. The coupling configuration is formed with sleeve having a first and a second coupling region, and a further mounting tubelet. The first coupling region holds the mounting tubelet, and the second coupling region holds the further mounting tubelet. The further mounting tubelet is plugged at one of its ends onto a ferrule end, projecting from the first mounting tubelet, and is centered with respect to that end. The other end of the second mounting tubelet serves for holding the plug pin of an optical plug. The invention permits mechanical decoupling of the operation of plugging and coupling a plug pin from the operation of adjusting and positioning the light-guiding structures contained in the waveguide tubelet.

The invention relates to an electro-optical module for transmitting and/or receiving optical signals on at least two optical data channels which are carried in an optical waveguide. The optical waveguide in the module forms at least two optical waveguide sections, with each section having at least one inclined end surface. The inclined end surfaces of the optical waveguide sections are positioned axially one behind the other. Light is injected into or light is output from the optical waveguide for a specific optical data channel by light for the optical data channel being passed to an inclined end surface, or emerging from it, at an angle to the optical axis of the optical waveguide.

The optic coupling system links a fiber-optics waveguide with two optoelectronic components. The components are disposed on a substrate with an interposed beam-splitting layer. The light incidence or light emission surface of the first optoelectronic element is disposed perpendicular to the substrate. The coupling system is either a bi-directional transmitter and receiver module or a mono-directional transmitter or receiver module. To this end, the light incidence or light emersion surface of the second optoelectronic element is disposed in parallel to the substrate and the beam-splitting layer is disposed on a surface that is arranged above the second optoelectronic element at an angle of approximately 45&deg; with respect to the substrate.

Optical coupling configuration

The module for optical signal transmission has a transmitting or receiving component mounted on a carrier. At least one optical waveguide, whose two ends represent an optical input and an optical output of the module, is associated with the transmitting or receiving component. A wavelength-selective element is arranged or formed in the optical waveguide and injects into the optical waveguide or outputs from it light, which is emitted from or received by the transmitting or receiving element, for a specific optical data channel. The light is injected into or output from the optical waveguide essentially at right angles to the optical axis of the optical waveguide.

Module for optical signal transmission

The transmission device comprises a transmission unit ( ) having a plurality of useful lasers ( to ), which are arranged in a row ( ) and emit useful radiation vertically with respect to the covering area ( ) of the transmission unit. In order to regulate the useful radiation power, a monitor receiver ( ) is arranged on a mounting plane ( ) which is laterally adjacent to the transmission unit ( ) and lies above the covering area ( ). The monitor receiver projects above an assigned monitoring laser ( ) like a cantilever support in such a way that its radiation-sensitive area ( ) is opposite the optically active zone ( ) of the monitoring laser ( ).

Multichannel optical transmitter

A coupling configuration is described which contains optoelectronic elements having optically active zones, a coupling element, and optical waveguide sections for coupling to each of the optoelectronic elements. The optical waveguide sections is disposed in the coupling element, the optical waveguide sections are disposed in at least two planes including a first plane and a second plane. The optical waveguide sections of different ones of the two planes are offset in relation to one another. Optical coupling paths run between the optical waveguide sections and the optically active zones. At least some of the optical coupling paths allocated to the optical waveguide sections of the first plane pass through intermediate spaces that exist between the optical waveguide sections of the second plane.

Configuration for coupling optoelectronic elements and fiber arrays

A module contains a plurality of optical transducers with optically active zones. The transducers are assigned an integrated circuit. A coupling assembly contains a plurality of optical channels running between an inner optical interface with the optically active zones and an outer interface. The transducers, the circuit and the coupling assembly are disposed together on a lead frame having connections for external contact-making.

Module for parallel optical data transmission

A fiber-optic endpiece includes a base member and a fixing member which can be inserted in the base member. The base member has a coupling end face and a depression with a bottom surface and lateral guide structures. The bottom surface has a groove for accepting an optical waveguide. The depression, the groove, and the optical waveguide extend to the coupling end face. The fixing member has a front face, a rear face and guide faces. The guide faces interact with the guide structures such that the fixing member is clamped in the depression. The optical waveguide is thus clamped between the base member and the fixing member when the fixing member is inserted. The coupling end face of the base member and the front face of the clamped fixing member lie in a common plane when the fixing member is in an inserted position. The depression and the fixing member have respective cross sections which diminish uniformly along a longitudinal direction of the depression. The side with the reduced cross section is disposed opposite from the coupling end face.

Fiber-optic endpiece

A coupling module contains a plurality of optical transmitters with an optically active zone in each case. Each transmitter is assigned an optical fiber end with a sloping end face that deflects radiation emitted by the transmitter. In order to set a desired damping, the end faces are provided with a coating that effects damping of the radiation.
