Abstract: Optical device and optical component part for the targeted reproduction of light emitted by LED light sources (6). The optical device comprises at least two component parts, a first optical component part (10) in the form of a solid waveguide and another component part for connection to the LED light source (6). In a system of Cartesian co-ordinates, the first optical component part (10) has a length in the y direction shorter than or equal to its length in the z direction and shorter than or equal to its length in the x direction. An envelope of the first optical component part (10) projected in an x-y plane forms essentially a rectangle. Proceeding from an x-y plane, the optical component part (10, 10?) tapers in the z direction to maximum ¼ of the largest width measured along y (By, max), with any design of the y-z flanks of the optical component part (10, 10?).

Abstract: An optical device is disclosed for producing light lines. The optical device comprises at least one quasi point-like light source. The optical device further comprises a transparent, light guiding body configured such that light from the at least one quasi point-like light source is led through the body. The light from the at least one quasi point light source is beamed in at a first front end of the body, and is beamed out again essentially at an opposite, second front end of the body. Slot-like cavities provided in the body reform the beamed-in light in a manner such that the body acts as a combination of a reflector with lens optics and a light scatterer.

Abstract: A biochemistry analyzer includes, an attenuated total reflection prism, a sample cell disposed on a surface of the prism, a sample supplier, a device for disposing more objective molecules in the liquid sample to a near portion of the sample which is near the surface of the prism, an infrared light source for generating an infrared light which is transmitted to the attenuated total reflection prism, a detector for detecting the infrared light which is reflected from the prism after the far portion of the sample is solidified, and a computer for calculating signals from the detector. As the objective molecules are gathered near the prism, accuracy of the biochemistry analyzer becomes higher.
