Abstract
A portable spectral imaging microscope includes a probe head coupled via fiber optic cabling to a laser source and to a spectrograph. The probe head is coupled to a position controller that is mounted on a base suitable for positioning adjacent to a sample. The position controller has five degrees of freedom that permits one to adjust the position and direction of the probe head relative to the sample over a wide range of dimensions and angles. The entire probe head can be easily moved in order to precisely align the objective lens to stationary samples for simultaneous viewing and spectral analysis.
Claims13
A spectroscopic microscope for evaluating a characteristic of a sample, the microscope comprising:
- a source of spectral energy, a probe head having an objective lens for directing spectral energy from the source toward said sample, optical transmission elements within the probe head defining an optical path between the source of spectral energy and the objective lens, collection elements within the probe head coupled to the objective lens for receiving energy returned from the sample, an optical image collection device coupled to the collection elements for extracting a visual image of the sample, a spectral collection device coupled to the collection elements for extracting a spectral characteristic of the sample, a base adapted to be situated adjacent to the sample and a position controller coupled to the base and the probe head for adjusting the position of the objective lens with respect to the sample, the relative position being ascertained at least in part by observation of the visual image of the sample derived from the optical image collection device.
