Fluorescence excitation assembly and imaging system

Abstract

The utility model relates to a fluorescence excitation assembly and an imaging system, and the fluorescence excitation assembly comprises a first light source for emitting first laser, a second light source for emitting second laser, a third light source for emitting third laser, and an optical filter group for filtering the laser to a sample to be detected and exciting various types of fluorescence, and further comprises a first dichroscope, a second dichroscope, a third dichroscope, a first light source and a second light source, the first dichroscope is located on a propagation path of the first laser and the second laser, transmits the first laser and reflects the second laser; the second dichroscope is located on the light path of the first laser transmitted by the first dichroscope and the light path of the second laser reflected by the first dichroscope, and the second dichroscope transmits the first laser and the second laser and reflects the third laser; and the reflective mirror is located on the light path of the first laser and the second laser transmitted by the second dichroscope and the light path of the third laser reflected by the second dichroscope, and the reflective mirror is used for reflecting the first laser, the second laser and the third laser to the optical filter group. According to the utility model, the scanning efficiency of the slide is improved, and the scanning imaging quality is better.
