Abstract: An Echelle polychromator 50 has disposed upstream thereof a pre-monochromator 14 comprising a prism 20. The linear dispersion of the pre-monochromator 14 is variable by varying the angular dispersion of the prism 20. A particular spectral position and the close vicinity thereof are analyzed by an Echelle grating 54 with high resolution. Care must be taken that, on the one hand, the detector array 66 of the Echelle polychromator 50 is fully exploited in response to the central wavelength respectively observed and that, on the other hand, interfering orders are kept away from the Echelle polychromator 50. The linear dispersion of the pre-monochromator is variable for this purpose.

Abstract: The invention contemplates a two-dimensional spectrometer wherein a single catadioptric system is both the collimator and the camera for two-pass use of any two-dimensionally dispersed spectrometer. Off-axis aberration effects are minimized by arranging a fiber optic as the light-entrance aperture, on the central optical axis of the spectrometer and in close proximity to or centrally inserted in a two-dimensional array detector at the image plane. In other words, the grating of the spectrometer is also a reflector which folds admitted and dispersed light for return to the image plane along essentially the same path and through the same optical elements as are used on the incoming pass of light to the diffraction grating. The invention is shown for its applicability to each of various types of two-dimensional spectrometer-design configurations.

Abstract: An adjustable Echelle spectrometer arrangement which can be used in single- and multi-element analysis by the emission or absorption of optical radiation. To compensate all the manufacturing and setup errors, the only arrangements present are those to change the height of the entry slit arrangement above the base plate and to rotate the dispersion prism about a first axis, approximately parallel to its roof edge, and about a second axis, that is vertical thereto. This compensates for the effect of errors associated with component and setup parameters which results from greater tolerances, without impairing mechanical and thermal stability and imaging quality.

Abstract: Configurations for light source modules and methods for mitigating coherent noise are disclosed. The light source modules may include multiple light source sets, each of which may include multiple light sources. The light emitted by the light sources may be different wavelengths or the same wavelength depending on whether the light source module is providing redundancy of light sources, increased power, coherent noise mitigation, and/or detector mitigation. In some examples, the light source may emit light to a coupler or a multiplexer, which may then be transmitted to one or more multiplexers. In some examples, the light source modules provide one light output and in other examples, the light source modules provide two light outputs. The light source modules may provide light with approximately zero loss and the wavelengths of light may be close enough to spectroscopically equivalent respect to a sample and far enough apart to provide coherent noise mitigation.

Abstract: In an example, an Echelle grating wavelength division multiplexing (WDM) device includes a first waveguide, a slab waveguide, multiple second waveguides, an Echelle grating, and a metal-filled trench. The first waveguide includes either an input waveguide or an output waveguide. The multiple second waveguides are optically coupled to the first waveguide through the slab waveguide. The multiple second waveguides include multiple output waveguides if the first waveguide includes the input waveguide or multiple input waveguides if the first waveguide includes the output waveguide. The Echelle grating includes multiple grating teeth formed in the slab waveguide. The metal-filled trench forms a mirror at the grating teeth to reflect incident light from the first waveguide toward the multiple second waveguides or from the multiple second waveguides toward the first waveguide.

Abstract: A tunable ultra-compact spectrometer and methods for spectrometry therefor can include a single pixel and a Fresnel zone plate having a focal length at a first temperature T1 and a first wavelength λ1, and a focal point. The pixel can be twenty micrometers square and can be placed at a distance from the pixel that equal to the focal length so that the focal point is at the pixel. The Fresnel zone plate can be made of a material that causes the same focal point at the pixel at T2, but at a different wavelength λ2 than wavelength λ1. A heat source can selectively add heat to the Fresnel zone plate to cause a second temperature T2. Exemplary materials for the Fresnel zone plate can be quartz for visible wavelengths, silicon for infrared wavelength, or other materials, according to the λ(s) of interest.
