Abstract: A Littrow-type spectrometer or monochromator (10) using a folded light path to provide a compact optical instrument is disclosed. Light enters the instrument through an inlet aperture on a planar mirror (14). The aperture is located at the focus of a parabolic collimetor-mirror (18). Collimated light reflected by the parabolic mirror is reflected back to the planar mirror, which is positioned at an angle to the collimated light. The light reflected from the planar mirror is directed at a planar grating (20) that produces diffracted light having all the wavelengths input into the system, including light of a selected wavelength, back towards the planar mirror. Light having the selected wavelength is thus caused to fall on the parabolic mirror. The parabolic mirror then focuses the selected wavelength of light ont a light exit aperture that is juxtaposed to the inlet light aperture. The planar grating can be rotatably mounted to scan the input light spectrum.

Abstract: A spectrograph with a first concave spectrographic diffraction grating (16) is positioned to receive light from the input light source (12) is configured to provide a diffracted light output dispersing the components of the input light source in a first direction. The dispersion forms the input light into an intermediate spectrum. The intermediate spectrum is formed in a focal surface by the once diffracted light. A slit (18) is substantially positioned on the focal surface. A second concave diffraction grating (20) is positioned to receive once diffracted light from the slit and configured to provide a twice diffracted light output, the second concave diffraction grating dispersing the components of the input light source in a second direction. The second direction is different from the first direction, the dispersion forming the input light into an output spectrum.

Abstract: Spectrofluorometer (10) employing a pair of linear variable spectral filters (14, 18) to produce a three dimensional data output is disclosed. A collimated white light source (36) is used that first passes through a first linear variable spectral filter (14), then through a sample (16) where fluorescence occurs, then the resultant light passes through a second linear variable spectral light filter (18) that is oriented at ninety degrees from the first filter (14). The light is then detected by a CCD sensor (20) for conversion into data. This arrangement provides a very simple, rugged and compact instrument that can be used almost anywhere, such as at the scene of a contamination accident.

Abstract: A spectrometer which in one embodiment including a dispersive element and a concave element. The dispersive element may be a flat or concave grating which receives light and reflects the light in different collimated wavelengths. The concave element being located downstream from the dispersive element and arranged to reflect and focus the light toward a detector. The reflected light from the concave element including astigmatism. A cylindrical lens positioned between the concave element and the detector and configured to simultaneously correct the astigmatism and demagnify the light across the detector. In one embodiment the cylindrical lens varies in thickness progressively along its length.
