Near infrared chemical imaging microscope
First Claim
1. A chemical imaging system comprising a chemical imaging detection system and a visible imagery system, wherein said chemical imaging detection system comprises:
- a) an illumination source for illuminating an area of a sample using light in the wavelength selected from the group consisting of near infrared wavelength, infrared wavelength and visible wavelength;
b) a device for collecting a spectrum of transmitted, reflected or emitted light from said illuminated area of said sample and producing a collimated beam therefrom;
c) a detector for collecting wavelength filtered images of said collimated beam; and
d) a processor unit containing an algorithm for processing the wavelength filtered images wherein the algorithm deconvolutes the spectrum into one or more subspectra of transmitted, reflected or emitted light from at least two light transmitting, reflecting or emitting compounds.

Abstract
A chemical imaging system is provided which uses a near infrared radiation microscope. The system includes an illumination source which illuminates an area of a sample using light in the near infrared radiation wavelength and light in the visible wavelength. A multitude of spatially resolved spectra of transmitted, reflected, emitted or scattered near infrared wavelength radiation light from the illuminated area of the sample is collected and a collimated beam is produced therefrom. A near infrared imaging spectrometer is provided for selecting a near infrared radiation image of the collimated beam. The filtered images are collected by a detector for further processing. The visible wavelength light from the illuminated area of the sample is simultaneously detected providing for the simultaneous visible and near infrared chemical imaging analysis of the sample. Two efficient means for performing three dimensional near infrared chemical imaging microscopy are provided.
