Abstract: The invention describes an optical multiplexer for increasing optical data collection efficiency across at least two fields of view. The optical multiplexer includes a first optical path for operatively receiving optical data from a first field of view and at least one beam deflection system for operatively receiving optical data from at least a second field of view. The optical multiplexer also includes an optical train for focusing the optical data passing through the optical train onto adjacent sections of a focal plane array. The invention provides improvements including expanded across-track swaths, higher spatial resolution, imaging of real-time references on every frame, coincident imaging along separate paths, stereo imaging and other increases in imaging functionality.

Abstract: A multi-spectrum, multi-channel imaging spectrometer includes two or more input slits or other input for each input channel. The input slits are vertically and horizontally displaced from each other. The vertical displacements cause spectra from the channels to be vertically displaced on a single image sensor on a stationary image plane. The horizontal displacements cause light beams from the input channels to strike a convex grating at different incidence angles and produce separate spectra having different spectral ranges. A retroflective spectrometer includes a convex grating that, by diffraction, disperses wavelengths of light at different angles and orders approximately back along an incident light beam. A single concave mirror reflects both the input channel and the dispersed spectrum. A prism, set of mirrors, beam splitters or other optical element(s) folds the input channel(s) of a spectrometer to enable the input(s) to be moved away from the plan of the image sensor.

Abstract: The invention relates to a method for determining clinical and/or chemical parameters (S1) in a medium (10), comprising means (2), for example a laser unit, for emitting coherent light waves (6) and means (4), for example a phototransistor unit, for receiving light waves (8). According to said method, at least some of the emitted light waves (6) are transferred to the medium (10) and the means (4) for receiving light waves (8) measure at least some of the light waves (8) that are reflected in the medium (10), the parameters (S1) being determined as a result of the characteristics of the emitted and received light waves (6; 8). The fact that light waves (6) are emitted into the medium (10) by means of a laser unit (2) and that the light waves (8) that are reflected in the medium (10) are measured by means of a phototransistor (4) enables the parameters (S1) that occur in the target area of the laser beam to be determined advantageously in a processing and control unit.

Abstract: The invention relates to a filter unit (10) for filtering light comprising a first mask (3) with first cavities, a prism unit (7) and a second mask (8) with second cavities. The prism unit (7) is located between the two masks (3, 8), the first (3) and the second mask (8) having corresponding first and second cavities, which form cavity pairs. At least one second cavity in the second mask (8) is provided for each first cavity in the first mask (3). In addition, one prism is provided in the prism unit (7) for at least one pair of cavities. This produces an accurate, narrow-band filter unit. The invention also relates to an assembly comprising the filter unit and to a device for capturing images.

Abstract: The invention relates to an adjustable pinhole, especially for the illumination beam path and/or detection beam path of a laser scanning microscope. Said pinhole consists of at least two planar basic components comprising articulation points in the form of connecting elements, to which at least one cutting edge that can be displaced in one direction is applied. The basic components advantageously contain at least one integrated preferably optical or electromagnetic positioning element, and a device for preferably optical or electromagnetic position detection is provided on the blade or is connected to the same. The inventive pinhole is advantageously provided with two asymmetric openings oriented in opposite directions for the optical position detection and at least one light source radiates through said openings. A gap which is oriented preferably perpendicularly in relation to the direction of displacement is provided upstream or downstream of the openings and the quantity of light radiated through the gap is detected separately for each opening.

Abstract: The present invention relates to a double pass monochromator that improves wavelength resolution and reduces the actual length thereof. A return reflection means 7 that reverses the direction of dispersion of the wavelength of the second pass light 1c, 1f emitted and incident on a diffraction grating 4 during the reflection. In addition, the angles of the incident and emitted light during separation of spectral components by the diffraction grating are identical during the first and second diffraction.
