| 摘要 |
The present invention relates to an optical system (100) for performing scattering and absorbance assays in clinical diagnostics. The optical system (100) comprises a light source (60) for emitting collimated light (50) parallel to an optical axis (51) in an optical path (51'), a sample holding unit (21) comprising at least one sample holding position (22) being located in the optical path (51') and an optical detector (70) for measuring light transmitted through a sample (10) being located in a sample holding position. The optical system further comprises an adjustable light angle selector (55), wherein said light angle selector (55) is being adjusted to let small divergence of a collimated light to be detected when a scattering assay is being performed and wherein said light angle selector (55) is being adjusted to allow stronger diverging light to reach the detector (70) when an absorbance assay is being performed. |
