Abstract
Various turbidimeters are described that can detect light directly in a substantially circular, e.g., encompassing, manner such that an increased amount of scattered light from a sample vial may be detected by a light detector, e.g., a photodiode or photodiode array. In an embodiment, a substantially circular photodiode array is provided to directly detect scattered light in an arc about the sample vial. In other embodiments, light guides are provided in an arc element that guides light to a detector or detectors. Other aspects are described and claimed.
Claims7
A turbidimeter comprising:
- a cone-shaped collector;
- the cone-shaped collector having a collar for receiving a cuvette;
- the collar including a light entryway that encircles the cuvette such that scattered light from the cuvette will enter the collar;
- a base end of the cone-shaped collector;
- and a detector element adjacent to the base end;
- the cone shaped collector comprising surfaces that form an internal light path that internally reflects the scattered light along a periphery of the cone-shaped collector from the cuvette to the base where the detector element sits.
