Abstract

An arrangement which may be used for testing pharmaceutical or cosmetic substances, which are sealed in a testing room in a cabinet (100), with at least one elongated radiation source (14) such as a fluorescent tube arranged in the testing room, as well as at least one receptacle (12) such as a storage place for the samples. A mechanical filter is arranged between the radiation source (14) and the at least one receptacle (12), the mechanical filter extending along the radiation source and homogenizing light intensity impacting on the receptacle.

Claims

1. An arrangement for testing samples such as pharmaceutical or cosmetic substances comprising a cabinet (100) enclosing a testing room (10) with at least one elongated radiation source (14) such as a fluorescent tube arranged in the testing room, as well as at least one receptacle (12) such as a storage place for the samples,

wherein a mechanical filter is arranged between the radiation source (14) and the at least one receptacle (12), the mechanical filter extending along the radiation source and homogenizing light intensity impacting on the receptacle.

2. Arrangement according to claim 1, wherein the mechanical filter (18) is a slotted or perforated plate.

3. Arrangement according to claim 1, wherein the mechanical filter (18) relative to the receptacle (12) shows a concave and channel-shaped geometry, respectively, or a straight geometry.

4. Arrangement according to claim 1, wherein the mechanical filter (18) in cross section has a bent or open trapezoidal geometry.

5. Arrangement according to claim 1, wherein, in the testing room (10), several elongated radiation sources (14) running parallel to each other and forming a luminous field are arranged, and the mechanical filter (18) comprises a middle planar section (22) extending in parallel to the luminous field, as well as two outer sections (24, 26) being bent towards the receptacle (12).

6. Arrangement according to claim 1, wherein the mechanical filter (18) comprises a plurality of aligned elements.

7. Arrangement according to claim 1, wherein the mechanical filter (18) comprises sheet metal material.

8. Arrangement according to claim 1, wherein the mechanical filter (18) is a bent or folded sheet metal plate.

9. Arrangement according to claim 1, wherein the mechanical filter (18) is a plastic part.

10. Arrangement according to claim 1, wherein the mechanical filter (18) shows a geometry following in cross section a straight line.

11. Arrangement according to claim 1, wherein the mechanical filter (18) defines a planar surface.
