- the diaphragm body has a through bore both end faces along the optical axis, each with a lead through one of the electrodes Opening, each of the openings adjacent to a radiation exit window is arranged; an additional radiation source is arranged along the beam axis, radiation from the additional radiation source also being guided through the aperture opening becomes.
- From DE 195 47 813 C2 is also an electrodeless discharge lamp with an aperture body known.
- a plasma is created in the discharge vessel by coupling in a high-frequency one electromagnetic field is formed and radiation generated by the plasma emerges from the Discharge vessel through an area of the discharge vessel which is at least permeable to UV rays from, in the region of the plasma at least one diaphragm body made of high-temperature resistant Material is arranged, the at least one opening for constriction of the plasma region.
- the beam axis is provided with a flat electrode at each end; there at least one of the electrodes contains an opening in the region of the axis of the radiation exit, which is arranged adjacent to an exit window that is transparent to UV rays.
- the known discharge lamps prove to be problematic with regard to complete UV-Vis light sources for analysis purposes, with one lamp unit one deuterium and one Tungsten lamp in translucent arrangement, which together with shutter, SMA light guide connection and ballast for both lamps on a circuit board.
- a coupling optics - e.g. B. for fiber optics - must be in case of a possible Lamp replacement can be readjusted.
- the object of the invention is a simple and handy radiation source as a module to be specified, which is suitable for a circuit board structure with optical fiber coupling. Farther the radiation source should be exchangeable in a relatively simple manner, the replaced one Module is correctly adjusted.
- the object is achieved in that the additional radiation source within the module is fixedly arranged along the optical axis in a predetermined position, the module can be used in a holder of the lamp housing with a coupling optics, and within the bracket by positive locking of the module in relation to the coupling optics in one predetermined position is locked.
- the module points in the area of it for the purpose of locking Coupling optics face an annular adjustment element, which in relation on the first transparent body and the optical axis of the module in a defined Position is immovably adjusted.
- the adjustment element preferably engages in a recess in the holder for the coupling optics on.
- an adjustment ring is provided as the adjustment element, which is fixed in the recess by means of a screw.
- a temperature radiator is provided as an additional radiation source, and as an additional one Radiation source an incandescent lamp is used.
- Electrodes are provided, which, however, form a structural unit with the radiator module; the electrodes are arranged along the optical axis of the module, being in the Area of the optical axis have recesses for beam passage.
- the principal The structure of such a discharge arrangement is known from DE 195 47 519 or US 5,814,951 or DE 195 47 813 C2 known.
- the radiator module 1 has a hermetically sealed discharge space 2 with a Envelope made of quartz glass 4, the inside of three panels 3 made of high temperature resistant Contains material - such as molybdenum or tungsten - with the bezels each have an opening 5 along an optical axis 6.
- material - such as molybdenum or tungsten - with the bezels each have an opening 5 along an optical axis 6.
- dielectric Quadrat glass
- a first transparent body 12 recognizable as a window (quartz glass) which is transparent to UV radiation, through which by means of electromagnetic excitation in the discharge space 2 as plasma Radiation generated within the openings 5 emerges and into the recess 9 of the holder 11 arrives for the coupling optics 10.
- the coupling optics 10 supplies a connected one Optical waveguide 23 (shown broken) with radiation that emerges from the radiator module 1.
- the radiator module 1 has a further transparent one along the optical axis 6 Body 13 as a second window (quartz glass) that separates the discharge space 2 from a space 15 to accommodate a light bulb 16 as a thermal radiator.
- the transparent body 13 is at least transparent to visible radiation and infrared radiation, while the first transparent body 12 must also be transparent to UV radiation.
- the incandescent lamp 16 which is designed as a temperature radiator, generates a spectrum which is related to the Connects UVA range and extends to the infrared range, while that in the discharge space 2 generated UV radiation has the spectral range of UV-A, UV-B and UV-C.
- the spotlight module 1 has, in the area of the coupling optics 10, one which is fixedly connected to the radiator module 1 encircling ring 17, its position with respect to the optical axis 6 and the adjoining coupling optics 10 is adjusted so that the radiation from the incandescent lamp 16 and from the discharge space 2 on the way to the coupling optics 10 is optimized such that it can enter the optical waveguide 23 without major losses.
- the bracket 11 is on a circuit board 26 attached, on which the associated electronics is housed.
- the holder 11 for the coupling optics 10 (according to FIG. 1) with its recess 18 recognizable, in which the radiator module 1 is partially inserted so that the for Adjustment provided circumferential ring 17 positively inserted into recess 18 and locked in this position in holder 11 by means of a screw 21 recognizable with reference to FIG. 3 becomes.
- Ring 17 is not compared to the rest of the radiator module 1 using one here Recognizable recess positioned in the radiator module 1 so that after insertion of the radiator module 1 in bracket 11 always ensures an optimal adjustment of the lamp arrangement is.
- FIG. 3 shows the holder 11 arranged on a printed circuit board 26 for locking Radiator module 1 recognizable.
- the incandescent lamp which cannot be seen here, is along the optical axis 6 fixed in the lamp room 15 ( Figure 1), the radiation generated also emerges along axis 6 and through both transparent bodies designed as windows (Quartz glass) of the discharge space is guided. That of plasma balls in the area of the aperture 5 ( Figure 1) generated UV radiation also occurs along the optical axis 6 through the first transparent body 12 (quartz glass window) into the coupling optics 10, from where it is led into an optical waveguide 23 shown broken here.
