The first dichroic mirror is arranged at an irradiation light path of respective light sources. The color filter component is arranged at a transmission light path of the first dichroic mirror and includes at least one second dichroic mirror for receiving fluorescence signals. The fluorescence receiving component includes a plurality of optical elements, which are respectively arranged at a reflection and/or transmission light path of the second dichroic mirror. The application enables the simultaneous and instantaneous detection of multi-wavelength fluorescence.

Abstract: The present invention discloses an instantaneous multi-wavelength fluorescence detection instrument and an instantaneous multi-wavelength fluorescence detection method, relating to the field of medical instruments. The instantaneous multi-wavelength fluorescence detection instrument includes a card holder having an accommodating groove, a driving mechanism configured to drive the card holder to move, and an optical module for fluorescence detection. An optical module generates irradiation light of different wavelength by a light source. The irradiation light irradiates the sample to be detected through the first dichroic mirror to generate fluorescence signals of different wavelengths. The fluorescence signals form multiple fluorescence transmission paths through second dichroic mirrors, some of the fluorescence transmission paths are at a reflection light path of the second dichroic mirrors and some of the fluorescence transmission paths are at a transmission light path of the second dichroic mirrors.
