Title:
OPTICAL MICROSCOPE, AND SPECTROSCOPIC MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2012/124303
Kind Code:
A1
Abstract:
Provided are an optical microscope and a spectroscopic measurement method which enable high-resolution measurements to be made. A spectrometer in one embodiment of the present invention is provided with: a laser light source (10); an objective lens (21) that concentrates a light beam, and causes the light beam to strike a sample (22); a Y-scanner (13) that scans the spot position of the light beam on the sample (22); a beam splitter (17) that splits the emitted light emitted from the sample (22) to the objective lens (21) side, said emitted light having a different wavelength than the rest of the light beam that struck the sample (22), and the light beam from the light source (10) that strikes the sample; a spectroscope (31) that spatially disperses the emitted light split by the beam splitter (17) according to the wavelength; a detector (32) that detects the emitted light dispersed by the spectroscope (31); and a pinhole array (30) that is positioned on the incident side of the spectroscope (31), and upon which a plurality of pinholes (42), which allows the emitted light to pass through on the spectroscope (31) side, is disposed.
