  • Publication number: 20230266227
    Abstract: This disclosure relates to configurable particle analyzer apparatuses and methods. In some embodiments, a modular particle analyzer includes a stray light blocking module including a focusing lens, a pinhole, and a collimating lens. The focusing lens is configured to focus light emitted from the flowcell through the pinhole. The pinhole is configured to block stray or scattered light emitted from the flowcell. The collimating lens is configured to substantially collimate the light exiting the pinhole to output a substantially collimated light beam. A modular particle analyzer may alternatively, or additionally, include a rod-and-cage architecture. A particle analyzer may alternatively, or additionally, include a sheath pressure control module and a sample pressure control module. Further, a particle analyzer may alternatively, or additionally, include a sample probe wash. Any of the embodiments described herein may be combined with any one or more of the other embodiments described herein.
