Abstract
An apparatus is disclosed wherein laser radiation illuminates a sample using all reflective optics and wherein in-elastically scattered light from the sample is collected using the identical elements. The apparatus obviates the problem of contaminating the laser radiation with unwanted spectra from transmissive optics while providing very high rejection of the laser radiation with respect to the in-elastically scattered light. In addition, the apparatus can collect and launch light with high numerical aperture and large field of view.
