Definitions

  • Known lighting devices provide an oversupply of light, of which only a small part is used.
  • Powerful halogen lamps with a large lamp filament which generate a large geometric light flux, are used as light sources for such lighting devices.
  • the geometric light flow results from the large luminous area and the large beam (opening) angle of the halogen lamp.
  • an illumination device for a microscope in which no optical components are moved.
  • a light source is provided which illuminates a flat LCD. Any desired transparency is placed on the LCD by means of a control device.
  • Opaque pattern generated By changing the size of the pattern, the lighting can be adapted to different apertures.
  • software-controlled, different lighting conditions are set.However, it is also necessary here to provide a large geometric light flow through the light source, of which only a small part is used
  • the first light source 2 is arranged in the focal point of the collector axis 3, which has a parallel beam of illuminating rays! 17 generated This parallel illuminating beam 17 is guided over the first lens 10 The illuminating beams diverge at small angles through the diffusing screen 10. The beams are then deflected into the object plane 9 via the condenser lens 5.
  • This lighting corresponds to critical lighting and is used for an objective with a small field and a large aperture
  • the arrangement of the two light sources 2 and 8 produces only the geometric light flux that is used by the corresponding lens. This means that the high-performance halogen lamps used to date can also be dispensed with
  • a control device 13 is provided, which is connected via an electrical wiring harness 15 to the housing 12 and the two light sources 2, 8.
  • the control device 13 has a voltage source for regulating and operating the light sources 2, 8 a Battery 14 and a connection 19 for a voltage power supply unit It goes without saying that this battery can also be designed as a rechargeable battery that is operated whenever there is no mains voltage source
  • control device has a plurality of operating buttons 16, by means of which the two light sources 2, 8 can be switched either selectively or together. It is also provided that the respective lamp brightness can be controlled via the operating buttons 16. When using LEDs, the brightness can be adjusted simply by regulating the Current can be set without changing the color temperature of the lighting
  • Illumination device first light source - collector lens - aperture diaphragm - condenser lens - illumination beam path - central hole in 3 - second light source - object level - first diffuser - second diffuser - housing - control device - battery - electrical wiring harness 12-13 - control buttons - illuminating beams from 2 - illuminating beams from 8 - Power supply connector - optical axis

Abstract

L'invention concerne un dispositif d'éclairage (1) destiné à un microscope. Une première source lumineuse (2), une lentille de champ (3), un diaphragme d'ouverture (4) et un condensateur (5) sont placés dans le trajet du faisceau lumineux (6). La lumière d'éclairage est dirigée dans le plan (9) de l'objet en traversant la diaphragme d'ouverture (4) et en passant par le condensateur (5). Une deuxième source lumineuse (8) est placée dans le trajet du faisceau lumineux (6) sur l'axe optique (20) et est projetée à l'infini par le condensateur (5).
