Abstract:
1. An optical sensor comprising: a sensor head that includes a first optical window, a second optical window, at least one light source, and at least one detector, wherein the at least one light source is configured to emit light through the first optical window into a flow of fluid within a first optical region and the at least one detector is configured to detect fluorescent emissions through the second optical window from the flow of fluid within a second optical region; a flow chamber that includes a housing defining a cavity into which the sensor head is inserted, an inlet port configured to communicate the flow of fluid from outside of the cavity to an interior of the cavity, and an outlet port configured to communicate the flow of fluid from the interior of the cavity to back outside of the cavity, wherein the inlet port defines a first fluid nozzle and a second fluid nozzle that each project into a third optical region located between the first optical region and the second optical region, the first fluid nozzle is configured to direct a portion of the flow of fluid against the first optical window, and the second fluid nozzle is configured to direct a portion of the flow of fluid against the second optical window.
