    Abstract: The present invention provides a small spectrocsope that has a short response time. A spectroscope according to an embodiment includes a beam deflector that includes an electro-optic crystal, having an electro-optic effect, and paired electrodes used to apply an electric field inside the electro-optic crystal; spectroscopic means for dispersing light output by the beam deflector; and wavelength selection means for selecting light having an arbitrary wavelength from the light dispersed and output by the spectroscopic means. At the least, either an input end or an output end of the beam deflector is wedge shaped, so that a thickness of the end is gradually reduced from the first face, where the first electrode of the paired electrodes is located, toward the second face, opposite the first face, where the second electrode of the paired electrodes is located.

    Abstract: The present invention provides a method and apparatus incorporating a spinning, oscillating or stepping optical interference filter (109) to change the angle at which light (102) passes through the filters after passing through a sample (105) under analysis downhole. As each filter is tilted, the color or wavelength of light passed by the filter changes. Black plates are placed between the filters to isolate each filter's photodiode. The spectrometer of the present invention is suitable for use with a wire line formation tester to provide supplemental analysis and monitoring of sample clean up. The present invention is also suitable for deployment in a monitoring while drilling environment. The present invention provides a high resolution spectometer which enables quantification of a crude oil's percentage of aromatics, olefins, and saturates to estimate a sample's gas oil ratio (GOR). Gases such as CO2 are also detectable. The percentage of oil-based mud filtrate contamination in a crude oil sample can be estimated with the present invention by using a suitable training set and chemometrics, a neural network, or other type of correlation method.
