Abstract

Claims (29)

1 . A system for improving a reflectance spectrum of an optically diffusive sample, comprising:

an optical spectrometer;

a light source; and

an encasement, comprising:

(i) an outer surface;

(ii) an inner surface defining a cavity and at least partially enclosing said light source and said optical spectrometer in said cavity, wherein said outer surface, a ceiling of said inner surface, and a floor of said inner surface are in optical communication with said optically diffusive sample, and wherein said optically diffusive sample is positioned outside of said cavity.

2 . The system of claim 1 , wherein said floor of said inner surface has a reflectivity of at least about 98% over a range of wavelengths of light said optical spectrometer is configured to detect.

3 . The system of claim 1 , wherein said light source is configured to emit light within a cone having a half angle of at least about 60 degrees.

4 . The system of claim 1 , wherein said light source has a spectral bandwidth of at least about 10 nanometers.

5 . The system of claim 1 , wherein said floor of said inner surface comprises polytetrafluoroethylene.

6 . The system of claim 1 , wherein said outer surface is hemispherical.

7 . The system of claim 1 , wherein said encasement is configured to direct light reflected off of said inner surface or said outer surface away from said optical spectrometer.

8 . The system of claim 1 , wherein said floor of said inner surface comprises a diffuse reflective material.

9 . The system of claim 1 , further comprising an aperture disposed in said floor of said inner surface, wherein said light source is disposed within said aperture.

10 . A method, comprising:

(a) providing an optically diffusive sample;

(b) providing an optical spectrometer comprising a light source and an encasement, wherein said encasement comprises an outer surface and an inner surface, wherein said inner surface defines a cavity and at least partially enclosing said light source and said optical spectrometer in said cavity, wherein said outer surface, a ceiling of said inner surface, and a floor of said inner surface are in optical communication with said optically diffusive sample, and wherein said optically diffusive sample is positioned outside of said cavity;

(c) illuminating, using said light source, said optically diffusive sample, thereby generating sample data associated with said optical spectrometer; and

(d) detecting, using said optical spectrometer, said sample data.

11 . The method of claim 10 , wherein said optically diffusive sample comprises a solid optically diffusive sample.

12 . The method of claim 10 , wherein said optically diffusive sample comprises a liquid optically diffusive sample.

13 . The method of claim 10 , further comprising calibrating said optical spectrometer.

14 . The method of claim 13 , wherein said calibrating comprises providing a reference material to said optical spectrometer, at least partially encasing said optical spectrometer with said reference material, illuminating said reference material using said light source, and detecting a reference spectrum from said reference material.

15 . The method of claim 14 , wherein said reference material comprises a polytetrafluoroethylene material.

16 . The method of claim 13 , further comprising using said sample data and said reference data to generate an analysis of said optically diffusive sample.

17 . The method of claim 10 , wherein said outer surface is hemispherical.

18 . The method of claim 10 , wherein said outer surface is translucent.

19 . The method of claim 10 , wherein light from said light source interacts with said optically diffusive sample at least twice prior to said detecting.

20 . The method of claim 19 , wherein said light from said light source interacts with said floor of said inner surface at least once prior to said detecting.
