    Abstract: A compact spectrometer operable in a wavelength range of 4.5 or more microns includes an entrance slit, a collimating mirror, a grating, a focusing mirror and a first focal plane. At least some radiation passing through the slit follows an optical path in which at least some radiation passing through the slit is reflected by the collimating mirror onto the grating, which in turn reflects at least some radiation onto the focusing mirror, which in turn reflects and focuses at least some radiation at a first focal plane and onto the two-dimensional array of detectors. Each column in the two-dimensional array of detectors corresponds to a wavelength in the 4.5 or more micron range. The two-dimensional array includes a plurality of columns that collectively correspond to wavelengths spanning the 4.5 or more micron range, and each adjacent pair of columns in the two-dimensional array of detectors corresponds to two wavelengths that differ by an equal amount. The entrance slit, the collimating mirror, the grating, the focusing mirror and the first focal plane are positioned within a volume that is equal to or less than 192 cubic inches in size.

    Abstract: In a spectrophotometer, the following formula is stored in advance as a correction formula of a rotation angle in a correction formula storing portion; θ′=θ+A•sin (C1•θ+θa)+B•sin (C2•θ+θb)+θc, wherein C1, C2 represent coefficients theoretically determined in advance by a structure of a reduction mechanism, and A, B, θa, θb, θc are coefficients specific to the reduction device which are calculated based on measurement results of a plurality of bright line spectrums through fittings by a coefficient determining portion. In case a sample is measured actually, when a desired wavelength is set, a rotation angle correcting portion corrects a rotation angle θ corresponding to the desired wavelength to calculate θ′ by applying the above-stated correction formula, and then, controls a motor so that a diffraction grid is rotated by the angle θ′.

    Abstract: A spectrometer that provides the ability to combine the advantages of high resolution, compactness, ruggedness, and low-power consumption of Fabry-Perot (FP) tunable filter spectrometer, with the multi-channel multiplexing advantage of FT and/or grating/detector array. The key concept is to design and operate a tunable FP filter in a multiple-order condition. This filter is then followed by a “low-resolution” fixed grating, which disperses the filtered n-order signal into a preferably matched N-element detector array for parallel detection. The spectral resolution in this system is determined by the FP filter, which can be designed to have very high resolution. The N-order parallel detection scheme reduces the total integration or scan time by a factor of N to achieve the same signal to noise ratio (SNR) at the same resolution as the single channel tunable filter method. This design is also very flexible, allowing spectrometer systems with appropriate order N to thereby optimize the system performance for spectral resolution and scan integration time. In addition to the significant reduction in scan integration time, there are two other advantages to this approach. The first, because the FP tunable filter is designed and operated under n-orders, the fabrication tolerances of the FP filter cavity and operating conditions are significantly loosened.

    Abstract: A plurality of configurations is simultaneously formed in a material by a single laser beam having a desired distribution pattern of wavelengths. An input laser beam has an initial wavelength distribution pattern. The initial wavelength distribution pattern is adjusted or modified into a desired final wavelength distribution pattern. For example, the initial wavelength distribution pattern is a wide range of wavelengths in a single bell-curve distribution while the desired final wavelength distribution pattern has a specific number of sharp peaks each over a predetermined narrow range. The laser beam having the desired final wavelength distribution pattern is focused upon on a material. Because of the multiple peaks in the wavelength distribution, the laser beam is focused at a plurality of the focal distances. A number of structures is simultaneously formed in a material at the multiple focal points or at multiple locations/depths when the above laser beam is projected onto the material.

    Abstract: An optical reflection device for filtering and spatially positioning individual optical channels or wavelengths. The device includes a plurality of optical members with reflective surfaces and at least one reflective layer located on the reflective surface of each optical member. In addition, the plurality of optical members are interconnected in a manner such that the reflective surfaces are oriented at predetermined slopes with respect to one another. Each reflective layer is configured to reflect a particular wavelength or channel. The plurality of optical members are interconnected in a manner that allows each optical member to reflect an individual channel at a unique angle with respect to the other optical members. This configuration allows the optical reflection device to individually reflect and filter channels that are dispersed from some form of dispersing member, such as a prism or a diffraction grating.
