A portable ring-type fluorescence optical system for observing microfluidic channel and an operating method thereof are disclosed. The portable ring-type fluorescence optical system includes a photographic chip, a first polarizer, an objective lens, a ring-type fluorescent light source, a biological sample on a microfluidic chip, a second polarizer and a bottom illumination light source arranged in order from top to bottom. The ring-type fluorescent light source is used to generate a ring-type fluorescent light to the biological sample on the microfluidic chip. The objective lens is used to magnify a fluorescent image of the biological sample on the microfluidic chip to focus on the photographic chip. The first polarizer disposed under the photographic chip and the second polarizer disposed under the biological sample form a non-zero angle to each other to block reflected lights that the biological sample reflects the lights emitted by the bottom illumination light source.
