The all-fiber endoscopic probe has attracted more and more attention in Raman spectral medical applications due to its small size and low cost. However, the resolution, size, and working distance of the endoscopy probe are mutually restricted. We propose a fiber structure and simulate the effects of different structures on the resolution and working distance. The results show that the optimal reflector angle is 43°-48°, and the optimal reflector distance is 0 μm. The minimum spot is 7.2 μm, and the maximum operational distance is limited to 0.25 mm. Raman fiber probes have great potential in endoscopic detection.
