    Abstract: A Compact and Athermal VNIR/SWIR Spectrometer utilizes a slit, a Mangin lens, a pupil lens adjacent to the diffraction grating, corrector lenses, a beam splitter, field lenses and SWIR and VNIR FPAs. In examples, two corrector lenses are used. Some examples do not utilize field lenses and beam splitter, some examples utilize only the SWIR radiation spectrum. By balancing the powers of the optical elements and Abbe numbers of glasses as well as usage of aspheric surfaces combinations, a monochromatic and polychromatic aberrational correction is achieved; by balancing optical elements refractive indices change with temperature an athermalization is achieved. The overall length of the spectrometer does not exceed 4 inches, and in some examples it is 2.5 inches. A wide field of view and a low F number are obtained with an operating wavelength range from approximately 400 to 2350 nm. The spectrometer is particularly suited to airborne applications.

    Abstract: An optical sensing module, adapted to sense a characteristic of an object by a sensing beam, comprises a carrying substrate, a transparent cover having a reflective surface thereon, a side wall, an optical grating, and an optical sensor. The reflective surface has a light-transmissive opening that exposes a part of the transparent cover. The side wall is disposed around the carrying substrate and is located between the carrying substrate and the transparent cover. The optical grating is disposed on the carrying substrate and a position of the optical grating corresponds to the light-transmissive opening. The optical sensor is disposed on the carrying substrate and is located at a side of the optical grating, wherein the carrying substrate, the side wall and the transparent cover form a vacuum chamber. The optical grating and the optical sensor are disposed in the vacuum chamber.

    Abstract: An optical system and method comprising a diffraction grating which consists of diffracting elements spaced from one another by unequal distances. Correction of residual defocusing in the image produced by such a grating is accomplished by translating it along its surface. As one embodiment, a monochromator is constructed on which a self-focusing grating scans the value in wavelength which is transmitted between fixed slits by rotation of the grating about an axis fixed in space. Combined with a translation of the grating along its surface, such a monochromator produces a symmetrical image exactly in focus at the exit slit for all scanned wavelengths.
