Abstract:
1. A method for performing spectroscopy of a sample using a microspectrometer, wherein spectroscopy is performed across a desired analysis range of the sample and wherein a size of the desired analysis range exceeds at least one of a size and travel capability of a stage of the microspectrometer, the method comprising the step of: controlling movement of a supplemental stage coupled to the microspectrometer to position an extended optical path of the microspectrometer over a point in the desired analysis range, wherein the sample is supported by the supplemental stage and wherein the movement of the sample enables spectral analysis of the sample at the point, including the step of extending an optical reach of the microspectrometer to provide the extended optical path by coupling an extender device to a microscope of the microspectrometer; and controlling the microspectrometer to emit at least one laser pulse onto the point of the sample on the optical path and to perform spectral analysis of scatter wavelengths received in response to the laser pulse via the optical path.
