    Abstract: A device is provided for selectively filtering an incident beam of light. A first interference-filter array is arranged to separate the incident beam into a plurality of spectrally complementary beams. An array of configurable optical shutters is disposed along paths of the separated beams to selectively block transmission of respective separated beams. A second interference-filter array is arranged to combine the separated beams whose transmission has not been blocked in accordance with states of the configurable optical shutters to produce a filtered output beam of light.

    Abstract: Illuminators and systems are provided that permit the production of a beam of electromagnetic radiation having selected peak wavelength, bandwidth, intensity, pulse frequency and pulse duration for a variety of analytical and therapeutic applications. Multiple beam illuminators use filter elements arranged into filter arrays, having characteristic wavelength absorption properties. By providing a series of filter arrays formed into tracks having defined wavelength offsets, radiation passing through a portion of a track can be modified to include selected peak wavelength and bandwidth. Selection of peak wavelength(s) and bandwidth can be accomplished using mechanical interrupters, mechanical shutters, or electro-optical devices including liquid crystal device. Multiple output beams permit the coordinated illumination of a target, and sensors provide feedback regarding the effects of illumination on a target. Computer storage devices, programs, and controllers can provide easy selection of the characteristics of the output beams. Output beams can have a variety of different shapes and configurations, depending on the desired application.

    Abstract: In in-situ laser plasma spectroscopy (LPS) apparatus includes an enclosure for housing a laser energy source and associated signal coupling optics. A main fiber is attached to the enclosure at a first end of the main fiber, and attached to a probe at a second end of the main fiber. The main fiber is configured for transmitting input laser energy from the laser energy source to a target and for transmitting laser induced plasma emission signals back from the target. The probe has a single focal lens for directing the input laser energy from the main fiber to the target, and for directing the laser induced plasma emission signals from the target to the main fiber.

    Abstract: There is presented a multipoint measurement system comprising light sources (1, 2); a plurality of illuminating fibers (5, 6) for transmitting light from the light sources to a sample so as to illuminate a plurality of points of the sample (A, B); a plurality of receiving fibers (8, 9) for collecting light beams including transmitted, reflected, scattered light beams at the plurality of points; a beam selector (10) which comprises a rotatable disk (12) having an aperture for transmitting a light beam collected by one of the plurality of receiving fibers (8, 9) through the receiving fiber (11); and an MCPD (4). When the rotatable disk (12) is rotated so that the aperture is displaced to and stops at a position at which light at the desired channel passes through, it is possible to perform measurement only on the light passing through the corresponding receiving fiber (8, 9, 11). Light at any other channel may be measured by rotating the rotatable disk (12) by a predetermined angle.

    Abstract: There is provided a monochromator capable of downsizing thereof. According to a monochromator, a light transmission hole through which beam of light which is given out from a light source is transmitted and multiple plate-like filter blocks each having central axis of rotation which is parallel with beam of light are provided on a filter base. Various optical filters are attached to the holes of filter blocks and the filter block serves as a light shielding block. The filter blocks attached to the rotary shafts of motors are reciprocally rotated between a forward position of the optical transmission hole serving as a position of transmission of light and a standby position spaced away from the optical transmission hole so that the filter blocks can be downsized, and even if there are many patterns of combination of optical filters, multiple optical filters can be easily combined with each other and even if the optical filters are used singly or used while combined with each other, which does not take time for changing the optical filter, thereby enhancing efficiency compared with the conventional monochromator.

    Abstract: An ellipsometer, and a method of ellipsometry, for analyzing a sample using a broad range of wavelengths, includes a light source for generating a beam of polychromatic light having a range of wavelengths of light for interacting with the sample. A polarizer polarizes the light beam before the light beam interacts with the sample. A rotating compensator induces phase retardations of a polarization state of the light beam wherein the range of wavelengths and the compensator are selected such that at least a first phase retardation value is induced that is within a primary range of effective retardations of substantially 135null to 225null, and at least a second phase retardation value is induced that is outside of the primary range. An analyzer interacts with the light beam after the light beam interacts with the sample. A detector measures the intensity of light after interacting with the analyzer as a function of compensator angle and of wavelength, preferably at all wavelengths simultaneously. A processor determines the polarization state of the beam as it impinges the analyzer from the light intensities measured by the detector.

    Abstract: An infrared spectrometer for the determination of isotopic ratios of gaseous compounds includes a broad-band infrared light source, a spectral selector, a sample compartment, an infrared detector, and a processor. The spectral selector selectively transmits a wavelength window of infrared light covering a range of wavelengths in which the wavelength window can be selected alternatively to overlap with a wavelength range primarily absorbed by a compound with a first isotope or by the compound with a second isotope. The sample compartment holds a gas sample and includes a gas inlet and a gas outlet. The infrared spectrometer can be used to detect isotopic ratios of carbon dioxide, where enhancement of 13CO2 can indicate metabolic activity of an infection, for example by H. pylori, or of specific enzymes. Preferred embodiments use a particular multipass optical cell that includes a field mirror and a multi-segment objective mirror.
