Abstract: A fiber optic probe is provided with a distal sampling end, a proximal end, and light delivery and collection paths therethrough. The probe includes a window disposed at the distal sampling end of the fiber optic probe, the window having a distal end and a proximal end, the window having a light blocking material that reduces a surface area that receives light rays. A lens is disposed near the proximal end of the window, the lens having a distal end, a proximal end, and an aperture. A light delivery optical fiber is provided having a distal end and a proximal end, the light rays being directed through the aperture. A collection optical fiber is provided in optical communication with the lens and the window. The probe may include a lens collection filter disposed between the window and the lens.

Abstract: The technology provides a spectroscopy system having two or more spectrometers with substantially uniform focal lengths. The spectrometers include a detector that converts optical signals into electrical signals to render spectral data. The spectroscopy system includes a computing device that is electrically coupled to one or more detectors to receive the spectral data and compare the spectral data against other spectral data. The other spectral data originates from spectrometers that have substantially similar focal lengths, slit widths, excitation laser wavelengths, or any combination of these. The technology includes an application server that is communicatively coupled to a second spectroscopy system. The application server includes software that enables data sharing among the two or more spectroscopy systems, including sharing the spectral data and the other spectral data. The application server compares sampled spectral data against stored spectral data to identify a match.

Abstract: The technology provides two or more spectrometers with substantially uniform focal lengths. A method includes adjusting a size of a first air gap associated with a first lens in order to modify a first focal length and securing a relative position of a first body and a second body of the first lens to set the first focal length at a first value for a first spectrometer. The method further includes adjusting a size of a second air gap associated with a second lens provided in a second spectrometer in order to modify a second focal length and securing a relative position of a first body and a second body of the second lens to set the second focal length at a second value for a second spectrometer. The first and second values are selected to render the first focal length substantially equal to the second focal length.

Abstract: The technology provides two or more spectrometers having uniform focal lengths that facilitate comparing spectral results obtained therefrom. The spectrometers include a collimating lens that receives light rays therethrough, a grating that is optically coupled to the collimating lens, and a focus lens that is optically coupled to the grating. The focus lens includes an outer body having a first lens set, an inner body having a second lens set, and an air gap defined between the first lens set and the second lens set. The inner body is moveable relative to the outer body to adjust a size of the air gap in order to modify a focal length of the focus lens. The inner body moves relative to the outer body to change an image size in the x-dimension. A fastener is provided to fixedly secure the inner body and the outer body.
