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.

Abstract: A light beam (6) is applied to a waveguide (3) in order to measure properties of the beam (6), e.g. the wavelength. According to the invention, the waveguide (3) has locally and/or time-varying resonances, e.g. by suitably designed grid couplers (4, 5). A light signal (7) is thus generated in the waveguide (3) as a direct measurement of the property to be measured and can be further processed by suitable means or evaluated. It is thus possible, for example, advantageously to produce a simple and inexpensive spectrometer.

Abstract: Gases can be selectively detected by the utilization of a infrared spectrometer via their specific absorption in the infrared spectral range. The sensor of the present invention is developed for continuously controlling a gaseous stream or a space filled with gas with the sensor being a single-piece shaped part manufactured as a microstructured body. The space filled with gas to be tested is between a mirror grating and entrance and exit slits for IR-radiation. The sensor is compact and robust, suitable for portable instruments, and can be manufactured at low cost and in large numbers. The sensor can also be made of metal and can be used even at an increased temperature. By using the sensor of the present invention, the safety of systems in which flammable, toxic or other gases are contained or may occur can be considerably increased in an economic manner.

Abstract: A method of making a corrected plane holographic grating within one band of wavelengths, intended for use in a diffraction apparatus in which light emitted by an entry source (1) is collimated by a spherical mirror (2) to the grating (4), which reflects parallel pencils to another spherical mirror (7), a focusing mirror, is disclosed. An auxiliary holographic grating (25) is created by the interference on a spherical surface (15) of a parallel pencil of light produced by the spherical mirror (7) subsequent to reflection onto a plane mirror (12) and of a divergent pencil deriving from the center of the surface (15). The auxiliary grating, corrected by the interference on a plane surface (22) of a parallel pencil produced by the spherical mirror (2) and of another parallel pencil produced by the auxiliary grating (25) illuminated from the center of the spherical surface, is then recorded.

Abstract: A plane-grating monochromator is described which is particularly well suited for wavelengths in the range from approximately 1 to 15 nanometers and contains as its primary optical elements a diffraction grating (16) and an ellipsoid mirror (20). If both the entry aperture and the exit aperture are intended to be stationary, then a pivotable mirror (14) preceding them is provided. The present plane-grating monochromator is distinguished by an accurate image, virtually free of distortion, and correspondingly high resolution as well as by simple optics; it includes only two or three optical elements, and a kinematically simple adjusting mechanism for the optical elements suffices for adjusting the wavelength.

Abstract: A high efficiency laser spectrum conditioner for generating a collinear parallel output beam containing a predetermined set of frequencies from a multifrequency laser. A diffraction grating and spherical mirror are used in combination, to disperse the various frequencies of the input laser beam and direct these frequencies along various parallel lines spatially separated from one another to an apertured mask. Selection of the desired frequencies is accomplished by placement of apertures at locations on the mask where the desired frequencies intersect the mask. A recollimated parallel output beam with the desired set of frequencies is subsequently generated utilizing a mirror and grating matched and geometrically aligned in the same manner as the input grating and mirror.

Abstract: Coupling optics is located in the beam path between intermediate slits S.sub.2 and S.sub.3 of an additive dispersion, double-pass monochromator, for imaging S.sub.2 onto S.sub.3 and for re-imaging an aperture stop back on itself, the stop defined by dispersing means. The slits S.sub.2 and S.sub.3 along with entrance and exit slits S.sub.1 and S.sub.4 may have curvature defining a circle.
