Patent ID: 7952706

Claim:
A multiple channel optical spectroscopy system, comprising: a plurality of optical channels, wherein each of at least two of the plurality of optical channels collects optical signals from unique locations, wherein each of at least two of the plurality of optical channels comprises: an integrated optics module comprising: a dichroic beam splitter selected to pass light of a wavelength for illumination of a sample and reflect light in a wavelength region of interest for analysis; a laser line filter disposed to pass a narrow wavelength band of light toward and through the dichroic beam splitter illuminate a sample for analysis, and a long-pass edge filter disposed to receive and pass light reflected by the dichroic beam splitter after returning from illuminating the sample; a sample-side optical fiber connected on one end to the integrated optics module and adapted on the other end to connect to a multiple channel optical probe, such that laser light is deliverable to a sample via the sample side optical fiber and light collected from a sample is deliverable to the dichroic beam splitter via the sample side optical fiber, a light source-side optical fiber operably connectable to a light source on one end and connected to the integrated optics module at the other end, such that light from the light source is deliverable to pass through the laser line filter towards and through the dichroic beam splitter to illuminate a sample; a spectrometer-side optical fiber configured to deliver light collected from a sample by the sample side optical fiber and reflected by the dichroic beam splitter to a spectrometer; a single optical spectrometer configured to simultaneously receive and simultaneously separately measure optical spectra including a range of wavelengths from more than one spectrometer side optical fiber; and a laser light source configured to simultaneously launch light into multiple optical channels.
