Device for optical characterization
A device for optical characterization of a sample is provided, the sample being accommodated in a receptacle container transparent to light. The device includes a camera, using which the sample may be detected, and a first light source is situated in such a way that the sample is transilluminated opposite to the viewing direction of the camera, a second light source is situated on the same side as the camera, and a laser source is situated transversely to the viewing direction of the camera.
1. A device for optical characterization of a sample accommodated in a receptacle container transparent to light, the sample being detected by a camera, the device comprising: a first light source situated in such a manner that the sample is trans-illuminated opposite to the viewing direction of the camera; a second light source situated on the same side as the camera; at least one laser source situated transversely to the viewing direction of the camera;
a screen positioned in such a manner that a projection of a laser beam from the laser source, which laser beam has penetrated the sample, is detected on the screen by the camera; and
at least one further laser source situated transversely to the viewing direction of the camera.
2. The device as recited in claim 1 further comprising: a mirror situated below the sample, wherein the mirror enables viewing of the bottom of the sample.
3. The device as recited in claim 1 , wherein laser beams emitted by the laser sources penetrate the sample in such a way that projections of the laser beams are detected adjacent to one another on the screen by the camera.
4. The device as recited in claim 3 , wherein the laser sources generate laser beams having different wavelengths.
5. The device as recited in claim 3 , further comprising:
a UV source for irradiating the sample; and
a detector configured to determine at least one of luminescence and fluorescence of the sample.
6. The device as recited in claim 3 , further comprising:
a device for recording infrared radiation, wherein the device for recording infrared radiation is situated in such a manner that infrared radiation originating from the sample is recorded.
7. The device as recited in claim 6 , wherein the device for recording infrared radiation is an infrared-sensitive camera.
8. The device as recited in claim 7 , further comprising:
a device for emitting an infrared flash onto the sample.
9. The device as recited in claim 6 , further comprising:
at least one tunable filter element, wherein the filter element enables separation of the recording into individual spectra.
10. The device as recited in claim 9 , wherein the at least one tunable filter element is situated between the sample and the camera.
11. The device as recited in claim 9 , wherein the sample is rotatably accommodated in the receptacle container.
