Abstract: This invention relates generally to slits used in optics that must be precisely aligned and adjusted. The optical slits of the present invention are useful in x-ray optics, x-ray beam lines, optical systems in which the entrance slit is critical for high wavelength resolution. The invention is particularly useful in ultra high vacuum systems where lubricants are difficult to use and designs which avoid the movement of metal parts against one another are important, such as monochrometers for high wavelength resolution with ultra high vacuum systems. The invention further relates to optical systems in which temperature characteristics of the slit materials is important. The present invention yet additionally relates to precision slits wherein the opposing edges of the slit must be precisely moved relative to a center line between the edges with each edge retaining its parallel orientation with respect to the other edge and/or the center line.

Abstract: An entrance slit and exit slit of a monochromator is shaped so that the width of the slits becomes smaller from the center towards the ends of their height, where the width is a dimension in the direction of the separation of the light in the monochromator. An example of such shape is rhombic. When the total amount of light emitted from the monochromator and the resolution of the monochromator are set to be the same, the efficiency of light in measuring small samples is increased and the ratio of stray light in the light emitted from the monochromator becomes smaller.

Abstract: An optical scanning device, such as a chromatoscanner, includes a spectroscope having a rectangular outlet slit for producing a light beam in the shape thereof. A rotatable disk having a spiral slit is disposed in the path of the light beam to produce light pulses along radial lines of the disk which are directed to the surface of a specimen. The absorbancy of the light pulses at discrete positions of the specimen is measured and stored in a memory in accordance with the corresponding location on the specimen as derived from measuring the rotation angle of the disk.

Abstract: A spectrum analyzer is disclosed which is of the type that utilizes an electrically scannable array of optical detectors. The array is selectively illuminated, i.e. irradiated, by at least two portions of a spectral band image of radiation. One of the portions is associated with a first spectral range and the other portion is associated with a second spectral range. The first and second ranges include mutually exclusive first and second spectral components, respectively, and a common third spectral component which is intermediate of the other two components. The detectors are calibrated by means which include a pair of optical filters. One of the filters is a single narow band transmission which has a transmission characteristic corresponding to one of the three aforementioned spectral components. The other filter is a double, i.e. two, narrow band transmission filter which has a transmission characteristic corresponding to the other two spectral components. In this way, the number of calibrating filters used in the system during the calibration mode is minimized and simplified than would otherwise be the case if a separate filter for each of the three spectral components were to be utilized.

Abstract: A rapid scan spectrum identifier fur use in identifying infrared spectrum of the output of a gas chromatograph to identify its absorption characteristics and includes an infrared source and beam splitter, a double beam chopper for alternately sending the infrared beam through a sample or reference gas cell mounted in a suitable furnace, the output of which is recombined and analyzed by a monochromator having a narrow output passband of energy detected by a rapid response detector, the output of which is processed by suitable electronic circuitry to provide a readout. The monochromator is of the scanning type in which a grating is synchronously scanned with a circular variable filter so that the first order output of the grating is selectively passed and higher orders rejected by the filter. The sample and reference gas cell furnace assembly utilizes specially constructed sample and reference gas cells symmetrically mounted in a furnace arrangement for maintaining input gas streams at equal temperatures within each cell and above the temperature of condensation of the sample under investigation. The beam chopper contains associated photoelectronics for physically determining the location of a chopping blade to thereby provide gating signals for indicating the presence at the detector of a sample, reference, or a background signals. These grating signals are used in sample and hold circuits to convert an essentially digitally sampled output into a relatively smooth continuous curve indicative of the absorption of the sample so that the readout represents the sample absorption characteristics corrected for reference for the carrier gas and background effects. The instrument is designed to operate with scan rates of approximately 6 and 30 seconds.

Abstract: IN A SCANNING MONOCHROMATOR OF THE DIFFRACTION GRATING TYPE, AN IMPROVED SLIT MECHANISM IS PROVIDED ADJACENT THE MONOCHROMATOR ENTRANCE AND EXIST PORTS. EACH SLIT MECHANISM INCLUDES A PAIR OF CLOSELY SPACED PARALLEL SLIT EDGES AND, ADDITIONALLY, INCORPORATES A PARALLELOGRAM ARRANGEMENT. THE PARALLELOGRAM ARRANGEMENT PERMITS THE SLIT EDGES FORMING A SLIT TO BE MOVED RELATIVELY TOWARD AND AWAY FROM ONE ANOTHER TO VARY THE SLIT WIDTH, BUT THE EDGES ARE ALWAYS MAINTAINED IN VERY ACCURATE PARALLELISM. A UNIQUE DRIVE ARRANGEMENT CONNECTS THE INLET PORT SLIT MECHANISM AND THE OUTLET PORT SLIT MECHANISM SO THAT AN INCREASE OR DECREASE IN THE SLIT WIDTH OF ONE CAUSES A CORRESPONDING INCREASE OR DECREASE IN THE SLIT WIDTH OF THE OUTER. A FURTHER UNIQUE DRIVE ARRANGEMENT PERMITS THE DIFFRACTION GRATING TO BE ADJUSTED AT EITHER NORMAL SCANNING SPEED OR AT RAPID SPEED.
