Abstract: The present invention relates to different types of micromirror spectrometers using MEMS (Micro Electro Mechanical Systems) for various applications in the UV, VIS, NIR and MIR wavelength regions. The invention enables a wavelength selection using micro scanning mirror and integrated grating on a much smaller scale than previously encountered conventional diffraction grating monochromators. Especially small designs are obtained via simultaneous usage of collimation optics for both spatial filters, by using entrance and exit slit apertures, which are located very close together. Until now, the spatial filters themselves are not part of the miniaturization. The utilization of the precision from this technology allows for reproducible slits with defined geometries and surface roughness and accurate spatial classification towards the rotation axis of the diffraction grating. Therefore the assembly and adjustment effort of the monochromator is reduced. Due to the option of additional slit apertures, several independent monochromator channels with crossed beam paths can be created; whereas all remaining optical elements (diffraction grating and collimator optic) are utilized together. Such additional channels can serve, for example, as reference measurements of a radiation source, or enable the direct optical control of the grating torsion angle as a monitoring channel. The goal of the invention is to define a simple design and arrangement for monochromators based upon micromechanical elements, which avoids all disadvantages described above.

Abstract: A compact, grating spectrometer (1A) particularly adapted for visual observation of the sun's spectrum, from the Calcium K line to the Fraunhofer B line, at very high dispersion. The numerical aperture of the spectrometer's collimating mirror is intentionally mismatched to the numerical aperture of the spectrometer's light-input device in order to exploit, by means of the exceedingly narrow width of the spectrometer's entrance slit (110), the high degree of coherence of the central region of the Airy disk formed by the light-input device. The resulting Fraunhofer diffraction illuminates totally, or nearly totally, the collimating mirror throughout the K-B interval. The human eye's dynamic range is compensated to maintain resolution at the lowest, light levels of the K-B interval. UV spill is suppressed. Both input-optics and slit are shielded against differential heating.

Abstract: Concentric spectrometers are plagued with internal reflections due to inherent nature of more than one optical surface possessing a common center of curvature. Reflections from optical surfaces arise when there is a difference or change in the refractive index of the media in which an optical beam or ray of a given wavelength is propagating. Internal reflections in concentric optical systems can produce a myriad of undesirable optical phenomenon at the image plane such as multiple images of an object, interference fringes, and stray light. As a result a loss in contrast or detection limit arise from such phenomenon in which light or detectable radiation that impinges on the image plane does not add to the formation of the intended image, (stray light). The present invention produces high quality images without the optical phenomenon(s) that arise from internal reflections by removing the reflected radiation from propagating through the optical system.

Abstract: An optical spectrometer system that includes an optical element having a two-dimensional, curved, reflective, low emissivity slit body, or surround, in which an imaging slit is formed. The optical spectrometer system includes a detector, such as an infrared detector, for example, disposed in a cavity at a focal plane thereof, an optical system in the cavity for focusing radiation onto the detector, and an entrance pupil disposed in the cavity. The curved slit body effectively and substantially eliminates out-of-field radiation from impinging upon the slit body, and its low emissivity greatly reduces self-emission from the slit body. The reflective slit body is a low emissivity element that images the detector back upon itself and passes background energy that falls within a cone defined by the entrance pupil. By using the two-dimensional curved slit body, a relatively small detector dewar or focal plane cooler may be employed in the optical spectrometer system to cool the detector. The two-dimensional curved slit body emits less than three percent of in-field radiation and permits virtually none of the radiation derived from walls of the cavity from being imaged at the detector. The curved slit body preferably has a torroidal shape, and is formed so that central rays are normal to the slit body at all points. The curved slit body images the detector back upon itself, thus minimizing background effects. Use of the curved slit body eliminates the need to cool the slit body and walls of the cavity.
