    Abstract: A Czerny-Turner spectroscope according to the present invention includes: a collimator mirror having a toroidal surface for reflecting a beam of light passing through an entrance slit to a plane diffraction grating; and a telemeter mirror having a cylindrical surface for reflecting and converging the beam of light reflected and separated by the plane diffraction grating to an exit. When a slit is placed at the exit, the straight generatrix is set substantially parallel to the exit slit. When a linear object (such as the separation channel of the capillary electrophoresis microchip) to receive a part of the spectrum of light reflected by the telemeter is placed at the exit, the linear object is set parallel to the straight generatrix. By this construction and configuration, the curving of monochromatic spectrum component at the exit is minimized, and the monochromatic light produced by the inventive Czerny-Turner spectroscope can pass the exit slit in full. Thus, when used, as the detector of a capillary electrophoresis microchip, stability and reproducibility of capillary electrophoresis measurements are achieved.

    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.

    Abstract: This invention is related to a monochromator which employs a spherical mirror, a traveling plane mirror with simultaneous rotation, and a varied spacing plane grating. The divergent beam from the entrance slit is converged by the spherical mirror located at the various positions in the monochromator depending of the inventive system. To provide the meaningful diffraction efficiencies and to reduce unwanted higher order lights, the deviation angle subtending the incidence and diffraction beams for the plane grating is varied with the position of the traveling plane mirror with simultaneous rotation located in the front or back of the plane grating with wavelength scanning. The outgoing beam from the monochromator goes through the fixed exit slit and has same beam direction regardless of the scanning wavelength. The combination of properly designed motions of the plane mirror and novel varied-spacing parameters of the inventive plane grating corrects the aberrations and focuses the monochromatic spectral image on the exit slit, enabling measurements at high spectral resolution.

    Abstract: The invention relates to a monochromator which disperses the light containing many wavelengths emitted from a source of light, and which takes out a given wavelength component only. The invention realizes a monochromator which can take out the light of a single wavelength maintaining a very high wavelength purity by using a plane grating C which can be easily manufactured maintaining a high precision and by employing a very simply constructed wavelength sweeping mechanism in which the distance between the incident slit A and the diffraction grating C as well as the distance between the exit slit B and the diffraction grating C are maintained constant, instead of using a concave grating that had been indispensable in the conventional monochromator adapted to the wavelength regions of from soft X-rays to vacuum ultraviolet rays.
