    Abstract: A diffraction grating and a prism with the appropriate characteristics are employed to provide a combined dispersive characteristic that is substantially linear over the visible spectrum. Radiation from the grating and prism is collimated by a lens towards a detector array. The or a telecentric stop between the grating and prism is placed at a focal point of the lens in a telecentric arrangement so that equal magnification is achieved at the detector array. If the detector array is replaced by a plurality of optical channels, a multiplexer/demultiplexer is obtained.

    Abstract: The invention features an optical medium for calibrating UV absorbance detectors, methods for making such an optical medium, and methods for calibrating UV absorbance detectors using such a medium. The optical calibration medium includes a gel-sol silica glass monolith with a rare-earth dopant therein. The rare-earth dopant exhibits at least one spectral feature in at least the far UV range. The constituents of the gel-sol silica glass monolith are selected so the rare-earth doped sol-gel glass monolith exhibits a transmittance in the far UV range so each distinct spectral feature of the rare-earth dopant in the far UV range is discernable. The transmittance in a particular embodiment is at least about 50% at about 250 nm. The rare earth materials selected for use as dopants are those exhibiting a wide range of spectral features, preferably over a range from about 190 nm to about 700 nm and more particularly exhibit at least one distinct spectral feature in the range from about 190 nm to about 300 nm. In a specific embodiment, the rare-earth dopant includes atoms of erbium, having spectral features in a range from about 190 nm to about 650 nm and a distinguishable far UV spectral feature at about 257 nm.

    Abstract: A monochromator is provided which reduces the amount of stray light striking the detector of the monochromator. A light source is provided which directs light to a source mirror. The source mirror reflects light from the light source through a filter and an entrance slit, and to a first monochromator mirror. The first monochromator mirror collimates the light and reflects it to a diffractive surface. The diffractive surface separates the light into its individual wavelength components. The separated light is directed from the diffractive surface to a second monochromator mirror. The second monochromator mirror directs the light to an exit slit. The present invention reduces stray light to the diffractive surface by tilting the second monochromator mirror off axis at an angle to prevent the reflected light from striking the diffractive surface or directing light out of the plane of diffraction. The exit slit must be at a sufficient elevation above the diffractive surface in the housing to receive the reflected light. The light passes through the exit slit to a sample mirror. From this sample mirror, light is directed through a beam splitter. A portion of this light passes through the beam splitter, through a sample to be analyzed and to a detector. The other portion of the light reflects off of the beam splitter and passes to a second detector. The light striking the first detector (sample detector) is compared to the light striking the second detector (reference detector) so that the properties of the sample may be analyzed.

Measured data also may be stored and/or organized as part of a patient data base. Such methods and implements may be desirably utilized for purposes of detecting and preventing counterfeiting or the like. Low cost and small form factor spectrometers, and methods for manufacturing the same, also are disclosed. Spectrometers and spectrophotometers embedded in printing and scanning and other type devices, as well as computer companion devices, scope-type devices and the like, also are disclosed.

    Abstract: A concentric spectrometer which reduces stray light and re-entrant spectra within the spectrometer. The spectrometer includes a non-direct optical path between the entrance slit assembly and exit aperture. Dyson and Offner concentric optical configurations are used to eliminate third-order aberrations The concentric optical system includes a light trap which mitigates or eliminate stray light due to reflection of light incident on the exit aperture region but which does not impinge on the active area of a detector optically coupled to the exit aperture. A two-dimensional area array detector concurrently senses a spectral signal corresponding to an input optical radiation signal and a signal corresponding to zero-input radiation, and the spectral signal is corrected according to the zero-input radiation signal.
