    Abstract: In the spectroscopy module 1, a light absorbing layer 6 having a light-passing hole 6a through which light L1 advancing into a spectroscopic portion 3 passes and a light-passing hole 6b through which light L2 advancing into a light detecting portion 4a of a light detecting element 4 passes is integrally formed by patterning. Therefore, it is possible to prevent deviation of the relative positional relationship between the light-passing hole 6a and the light-passing hole 6b. Further, since the occurrence of stray light is suppressed by the light absorbing layer 6 and the stray light is absorbed, the light detecting portion 4a of the light detecting element 4 can be suppressed from being made incident. Therefore, according to the spectroscopy module 1, it is possible to improve the reliability.

    Abstract: An optical instrument using a plurality of lasers (85, 87, 89, 91) of different colors with parallel, closely spaced beams (95, 97, 99, 101) to stimulate scattering and fluorescence from fluorescent biological particulate matter, including cells and large molecules. A large numerical aperture objective lens (111) collects fluorescent light (133, 135, 137, 139) while maintaining spatial separation of light stimulated by the different sources. The collected light is imaged into a plurality of fibers (123, 125, 127, 129) , one fiber associated with each optical source (95, 97, 99, 101) , which conducts light to a plurality of arrays of detectors (124, 126, 128, 130, 301, 303, 305) , with each array associated with light from one of the fibers (123, 125, 127, 129) and one of the lasers (95, 97, 99, 101) .A detector array (301, 303, 305) has up to ten detectors (160, 170, 180, 159, 169, 179, 189) arranged to separate and measure colors within relatively narrow bands by decimation of light arriving in a fiber (123) .A large number of detectors is mounted in a compact polygonal arrangement by using reflective transfer legs from multiple beam splitters (151, 161, 171, 181, 191, 201) where the transfer legs arise from a polygonal arrangement of beam splitters.

    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.

    Abstract: An accessory for a spectrometer for carrying out measurements of specular reflectance of a sample. The accessory is designed so that all components can be located in a housing and the sample can be located horizontally on a top-plate of the housing with the components disposed below the plane of that plate. The radiation can be arranged to be incident at a number of different angles on the sample and it can also be arranged that the radiation is directed to the detector without being incident on the sample.
