785nm is the golden wavelength for Raman spectroscopy analysis. The collimator's low loss and low divergence angle (≤0.5mrad) ensure the signal-to-noise ratio of Raman signals;
The 5.0μm core diameter is compatible with high-power (≤1W) near-infrared lasers, avoiding fiber ablation under high power;
Near-infrared light has strong anti-interference ability, making it suitable for testing complex samples (such as those containing water or fluorescent impurities).
