The granted patent (Publication Number: US11913868B2) discloses an apparatus comprising a first light detection module to demultiplex a first fluorescent light in a specific range of wavelengths. This module includes detectors, transparent blocks, micro-mirrors, and filters to reflect and pass light of different wavelength ranges towards the detectors. Additionally, the apparatus includes a second light detection module to demultiplex a second fluorescent light in another range of wavelengths, with similar components as the first module.

Furthermore, the apparatus includes an input channel that splits a fluorescent light beam into the first and second fluorescent lights. The input channel consists of a wavelength beam splitter, collimating lens, blocking filter, and focusing lenses to ensure the proper handling and focusing of the fluorescent lights. This innovative apparatus aims to efficiently separate and detect fluorescent lights in different wavelength ranges, allowing for precise analysis and measurement in various applications.
