    摘要： In an embodiment, an apparatus may include a light source, a beam manipulator, an optical component, an analyzer, and a detector. The light source may generate an incident light at a first frequency. The beam manipulator may include one or more polyhedron-shaped prisms that may deflect the incident light for focus at a plurality of points on a sample. The optical component may collect the deflected incident light, focus the collected deflected incident light at the plurality of points on the sample, and collect scattered light from the sample. The scattered light may include elastic scattered light and/or inelastic scattered light. The inelastic scattered light may have a second frequency that is shifted up or down from the first frequency. The detector may detect the inelastic scattered light and the analyzer may identify a substance contained in the sample based on the detected inelastic scattered light.
