| titleOfInvention | Filter element, light source module, multi-channel fluorescence illumination system and fluorescence microscope |
| abstract | The invention discloses a filter element, a light source module, a multi-channel fluorescence illumination system and a fluorescence microscope. The multi-channel fluorescence illumination system includes a filter element and a plurality of fluorescence excitation light sources circumferentially arranged outside the filter element. The first beam splitting film and the second beam splitting film with an intersecting structure are used to guide light to different light sources, respectively. The wavelength bands reflected by the first beam splitting film and the second beam splitting film are different, and the transmitted wavelength bands are overlapped, so that the light sources at different positions have different wavelengths. Different fluorescent lighting channels and the same light path. The filter element in the present invention can only use two dichroic mirrors, and the filter area can be narrowed in an intersecting manner, and when replacing the light source, only the matching light source needs to be adjusted according to the first beam splitting film and the second beam splitting film. It can be installed in the corresponding position according to the characteristics of the filter element, and the operation convenience of replacing the light source is improved without replacing the filter element. |
