Abstract: 503,167. Monochromators. SEABROOK, H. (Halle Nachfolger Optische Werkstõtten, B.) June 30, 1938, No. 19474. [Class 97 (i)] In a double monochromator a prism P is used in conjunction with either of two prisms P or P so that the dispersions 'are either similarly or oppositely directed. The tables for P and P are geared to rotate in opposite directions through the same angle as the table for P . All the rotations are produced by a handle W. Light enters the apparatus through a slit S and is reflected from the plane mirror R to the concave mirror H , which reflects it to the prism P . The mirror R behind the prism returns the rays to the mirror H , whence they pass through -the slot S to the mirror H . After passing through the prism P (or P ) they are returned by the mirror R (or R ) to the mirror R which reflects them through the slit S .

Abstract: 362,305. Spectroscopic monochromators. MILLER, C., 86, Soorstrasse, Charlottenburg, Berlin. April 15, 1931, No. 11181. [Class 97 (i).] A double monochromator comprises two sets of spectrum-producing parts with auto-collimation and with chromatically uncorrected imaging systems, so combined about an intermediate slit that light passes through the slit out of one set of parts into the other, a common means of wave-length adjustment being provided for the two sets of parts. The spectrum-producing parts shown comprise half prisms 12, 13 each having one refracting and one reflecting surface, and collimating lenses 14, 15, disposed on opposite sides of a slit carrier 2 having slits 3, 4, 5 in vertical alignment. The lenses and prisms are mounted on sliders 6, 7 which can be displaced simultaneously by a right-and-left handed screw 9, 10 operated by a drum 11 carrying a scale of wave-lengths. The prisms 12, 13 are mounted on pillars 27, 28 rotatably mounted on the sliders, these pillars being provided with arms 16, 17 which are spring-urged into contact with fixed pins 18, 19, so that rotation of the prisms is automatically produced when the sliders are displaced, to set the prisms for minimum deviation of the wave-length being used. The incident light is reflected by a prism 22 so as to pass through the slit 3 to be collimated by the lens 14, and is then dispersed by the prism 12 to be focused by the lens 14 as a horizontal spectrum across the slit 4. A narrow band, the wave-length of which is determined by setting the drum 11, passes through the slit and is received by the parts 15, 13 which effect purification of the light, monochromatic light being focused on the slit 5 and directed out of the apparatus by a reflecting-prism 23. The slits may be arranged side by side on the holder 2, or they may be arranged in different transverse planes on three separate holders. By turning the prism 13 so that its refracting edge is towards the rear instead of towards the front as shown, the system 15, 13 can be made to double the dispersion instead of purifying. The same effect can be produced without moving the prism 13, by providing a reversing prism adjacent the slit 4.

Abstract: An optical filtering device incorporates first and second prisms, the latter prism counteracting the angular dispersion of the former prism. A spatial light modulator provides a positionally variable optical stop located to block radiation within a wavelength interval and received from a location within a scene. Unobscured radiation from that and other scene locations passes to a camera, which produces an image on a display. Opaque pixels in the stop are positioned to block unwanted light source s. The invention attenuates potentially dazzling monochromatic radiation while retaining radiation at other wavelengths for imaging purposes.

Abstract: The appts. includes an ultra short pulsed light beam (501), divided (502) into a number of light beams (503,504,505) including a reference beam which is deflected (503) along a fixed optical path (d3), and the other light beams are deflected (504,505) towards the objects (S1,S2). The light beams reflected from the object are collected (502) and fed to a time gate (506) with the reference beam. An autocorrelation function of the pulses is produced by the time gate with maxima at time discrete positions corresp. to the transition time differences between the reflected beams. The separation of the objects is derived in a analyser (507) using the autocorrelation function.

Abstract: 1,038,273. Monochromator. CARL ZEISSSTIFTUNG [trading as ZEISS CARL]. May 10, 1965 [May 12,1964], No. 19711/65. Heading G2J. A monochromator comprises in an autocollimation arrangement, an entrance/exit slit defined by jaws 5, 6, a mirror 7 and a prism 2 with a mirrored surface 3, the prism and the jaw 6 being fixedly mounted on a turntable 1 with an axis of rotation 4 which extends perpendicularly through the optical axis of the beam of light which passes through the slit, and is parallel to the slit. On a change of wave-length which is effected by rotating the prism 2 on turntable 1, jaw 6 is also rotated altering the width of the slit, which enables the spectral band width of the transmitted radiation to be maintained approximately constant. The initial slit width may be altered by adjusting jaw 5.
