Abstract
A microscopic spectrometer having a separate optical path for masking light from a sample for spectrometric measurements. In the preferred embodiment, a beam splitter is disposed behind an object lens to form two branched optical paths. One of the optical paths is provided with masks at a point of focus along the path, allowing part of the image to be masked. The second optical path allows optical throughput and observation of the entire image. These two optical paths are rejoined, and a final image is obtained for visual inspection by synthesizing the two optical paths.
