Definitions

  • the invention relates to a light source for irradiating, generally using light, an object or preparation for analysis, comprising at least one lamp.
  • camera systems For the purpose of analysing DNA and RNA structures, proteins etc., use is made of camera systems (also designated as “imaging systems”).
  • an object normally in gel-form, such as a gel with nucleic acid or a gel with protein.
  • the object is irradiated, usually with light and preferably from the underside.
  • the object can be treated with a fluorophore, whereby an object radiated with a preferably monochromatic light produces a determined emission as a result of fluorescence.
  • the optimal wavelengths for radiation (“excitation maximum) and of the emission (“emission maximum”) are very close to each other.
  • the conducting means for the light connect to the emitting element at a distance from the side to be illuminated of the emitting element.
  • the conducting means can moreover be concealed by such a method of connection such that they do not form an obstacle during use of the light source.
  • the conducting means for the light connect to a plurality of sides of the emitting element, it is also possible in effective manner to homogeneously illuminate emitting elements with a larger surface area for lighting.
  • the side for illuminating is defined as upper side, it is possible to introduce the light on a plurality of sides of the emitting element and/or on the underside of the emitting element.
  • Figure 2 A shows a light source 15 in modular form with a housing 16 provided with a plug 17 with which the modular light source 15 can be coupled to a detection device functioning by means of irradiation of a preparation (which can also be designated an object), for instance for detecting fluorescent excitation.
  • a detection device functioning by means of irradiation of a preparation (which can also be designated an object), for instance for detecting fluorescent excitation.
  • drives 22 with which a filter of choice can be placed in radiation beams 20. The thus coloured light is caught in introducing elements 23 and carried to emitting elements 18 by means of the fibres (not shown).
  • Figure 3 A shows an embodiment variant as alternative to figures 2A and 2B of a light source 25 in modular form, which for the time being is preferred in practice to the embodiment variant shown in figures 2A and 2B of modular light source 15, with a housing 26 provided with a plug 27 with which the modular light source 25 can be coupled to a detection device making use of irradiation of a preparation.
  • the radiation beams 30 are fed directly into introducing elements 32.
  • the intercepted light is carried to heads 34 where the wavelength of the light is reduced to a limited bandwidth by filters 35.
  • Figure 3B shows a part of the light source 25 in modular form, shown in side view in figure 3 A.
  • a carriage 37 which is linearly displaceable in housing 26 by means of a linear drive member (not shown) is provided with a plurality of filters 35.
  • a filter 35 of choice with a desired limited bandwidth can be placed above a lifting arm 38.
  • a motor 39 provided with a cam disc 40 is driven to place the desired filter 35 between head 34 and the protruding part 36 of emitting element 28 counter to the bias of a compression spring 41.
  • the head 34 is mounted on a displaceable support 42.

Abstract

L'invention concerne une source lumineuse homogène plane (1, 15, 25) avec une largeur de bande devant être définie (par exemple inférieure à 60 nm), qui comprend au moins une lampe (2, 19, 29), un moyen conducteur (8, 33) pour connexion lumineuse avec la lampe (2, 19, 29), un élément émetteur (12, 18, 28) pour connexion lumineuse avec le moyen conducteur (8, 33) pour la lumière, et qui possède au moins une surface devant être illuminée de façon homogène, ainsi qu'un moyen de filtre (5, 6, 35) placé entre la lampe (2, 19, 29) et l'élément émetteur (12, 18, 28) pour sélectionner une largeur de bande de lumière devant être transmise. L'invention concerne également un dispositif de détection utilisant l'irradiation d'une préparation.
