Abstract

The invention relates to an analysis system for analysing a sample on an analytical test element (16), said system comprising: a measuring module (13 ) for performing measurements of a sample on the analytical test element (16), an optical module (1, 25) comprising a lens (2, 26, 27), and a diaphragm (3, 21) for focussing the light. The lenses (2, 26, 27) and the diaphragm (3, 21 ) of the optical module (1, 25) are combined to form a multi-component injecti on- moulded part (23) embodied as a single component.

Claims (12)

1. An analysis system for analyzing a sample on an analytical test element (16), comprising .cndot. a measuring module (13) for carrying out measurements on the sample on the analytical test element (16) and .cndot. an optical module (1, 25), which comprises a lens (2, 26, 27) and a diaphragm (3, 21), by which the light can be focused, characterized in that the lens (2, 26, 27) and the diaphragm (3, 21) of the optical module (1, 25) are combined as one piece in a multi-component injection-molded part (23).
2. The analysis system as claimed in claim 1, characterized in that the multi-component injection-molded part (23) is a two-component injection-molded part with a first, translucent plastic component and a second, opaque plastic component.
3. The analysis system as claimed in either of claims 1 and 2, characterized in that the diaphragm (3, 21) comprises a diaphragm body (4) of an opaque plastic and a diaphragm aperture (5), the diaphragm aperture (5) being filled with a translucent plastic.
4. The analysis system as claimed in claim 3, characterized in that the lens (2, 26, 27) consists of the translucent plastic.
5. The analysis system as claimed in claim 4, characterized in that the lens (2, 26, 27) and the diaphragm aperture (5) filled with the translucent plastic are combined in a continuous region (12) of the translucent plastic in the multi-component injection-molded part (23).
6. The analysis system as claimed in either of claims 1 and 2, characterized in that the diaphragm (3, 21) comprises a diaphragm body (4) of an opaque plastic and a diaphragm aperture (5), the diaphragm aperture (5) being a clearance in the diaphragm body (4).
7. The analysis system as claimed in one of claims 1 to 6, characterized in that the measuring module (13) contains the optical module (7), the optical module (7) serving for carrying out optical measurements on the sample on the analytical test element (16).
8. The analysis system as claimed in claim 7, characterized in that the measuring module (13) comprises a light source (19), z, detector (18) and a test element holder (15), which are arranged in such a way that light from the light source (19) can pass through a translucent region (12) of the multi-component injection-molded part (23) to a test element (16) arranged in the test element holder (15) and be reflected by the test element (16) through the translucent region (12) to the detector (18).
9. The analysis system as claimed in one of claims 1 to 8., characterized by a reading module (24) for reading optically coded data, the reading module (24) containing the optical module or a further optical module (25).
10. The analysis system as claimed in claim 9, characterized in that the reading module (24) also comprises a light source (28), a detector (36) and a magazine holder, which are arranged in such a way that light from the light source (28) can pass through a translucent region (38) of the multi-component injection-molded part (23) to a test element magazine (31) held in the magazine holder and be reflected by the test element magazine (31) through the translucent region (38) to the detector (36).
11. The analysis system as claimed in claim 10, characterized in that the light source (28) and the detector (36) are arranged on a printed circuit board (20), which is connected to the optical module (35).
12. A method for producing an analysis system for analyzing a sample on an analytical test element, the analysis system containing a measuring module and an optical module, the optical module comprising a lens and a diaphragm, characterized by the following steps:

.cndot. multi-component injection molding of the lens and the diaphragm in a one-piece multi-component injection-molded part and .cndot. positioning and mounting of the multi-component injection-molded part in the analysis system.
