    摘要: A downhole optical apparatus includes an LED source, reflectance and fluorescence detectors, a plurality of fibers, a dichroic mirror (DM), a beam splitter/coupler, a probe, a short-pass filter (SP), a dichroic long-pass filter (LP), and a lens. Source light filtered by the SP is fed to the DM which deflects light of desired wavelengths only. The deflected light is focused by the lens onto a fiber and is ultimately injected into an oil flow by the probe. Light reflected by oil or fluorescing therefrom is received by the probe, and split by the splitter. A small portion is received by the reflectance detector. A large portion is received by the lens and directed to the DM which deflects reflected light and passes light at longer fluorescing wavelengths. Passed light is further filtered by the DM and LP to eliminate remnants of the reflected light, and provided to the fluorescence detector.
