The 785nm near-infrared band has a power of 75mW, which is the "golden excitation wavelength" for Raman spectroscopy and can effectively suppress fluorescence interference (the fluorescence background excited by near-infrared light is low). The fiber core diameter is 5μm, and the light intake is larger than that of the 4μm model. Combined with high power, the Raman signal intensity is high.

Applications: Spectral analysis: Raman spectroscopy (near-infrared excitation suppresses fluorescence, suitable for the detection of organic substances and material components); Biomedical: near-infrared biological tissue imaging (strong penetration, minimal damage to tissues).
