  • Patent number: 4690521
    Abstract: A device and method are disclosed for making reference marks on a microscope slide. The device includes a member for mounting the device to a microscope. A marking nib is provided to selectively place a reference mark on the slide at a preselected position relative to an object of interest on the slide. A mechanism is further provided for maintaining the same preselected position relative to all objects of interest marked on a slide including a member for moving the nib in at least two generally orthogonally aligned directions within a horizontal plane to permit adjustment and calibration of the preselected position relative to the objects of interest. A plunger member activates the nib and selectively reference marks the slide. Finally, the device includes a mechanism for selectively varying the size of the mark and for automatically maintaining the size once selected.

  • Patent number: 4682864
    Abstract: In order to simultaneously observe a transparent object from two directions, first and second beam paths containing first and second images from two directions are separated using a prism to reflect the second beam path yet pass the first beam path. The length of the second beam path is caused to be different from that of the first beam path. Then the first and second beam paths are combined so that the first and second images may be viewed simultaneously. The different beam path lengths result in the first and second images being formed at the same position. As a result, the images carried by the first and second beam paths, both passing through a single objective lens, may be viewed simultaneously at a single location.

  • Patent number: 4681402
    Abstract: A method and means for projecting a secondary rainbow of natural configuration comprising an arcuate prism of greater than about 180.degree. of arc and optionally an arcuate prism orienting means. The primary and secondary refractive surfaces of arcuate prism are oriented such that they meet along the edge of said arcuate prism closest to that point at the center of said arc. The angle formed by the primary and secondary refractive surfaces of said arcuate prism are from about 25.degree. to about 75.degree., the "active range". When the prism is of polymethyl methacrylate (such as lucite) the refractive surfaces subtend an angle of greater than about 35.degree. and less than about 65.degree., the "particular active range". Prisms within the active range provide for the projection of a secondary rainbow of natural configuration when a light course of generally parallel rays of light is oriented at a position from less than about 30.degree.

  • Patent number: 4678289
    Abstract: The deflection of a light beam in two mutually perpendicular directions ensues by rotating two spindles which are hinged to a single deflection mirror and whose axes reside perpendicular to one another. The first spindle is hinged to the deflection mirror via a fork joint such that the trunnion axis of said fork joint and the axis of the first spindle are perpendicular to one another. The second spindle is hinged to the deflection mirror via a turning arm and a dog secured to the backside of the deflection mirror. So that the two spindles can be turned independently of one another, the dog is guided in the turning arm so as to be freely pivotable around the axis of the first spindle. The dog is preferably guided in a slot of the turning arm. Apparatus equipped with only a single deflection mirror for the deflection of a light beam in two mutually perpendicular directions are usefully employed in laser labeling.

  • Patent number: 4676598
    Abstract: Apparatus for projecting a laser beam to provide simultaneously a stationary reference beam and a moving reference beam, which rotates in a plane normal to the stationary reference beam, includes a beam diverting arrangement for intercepting a primary beam and for splitting the beam into the two reference beams. The beam diverting arrangement includes first and second deflecting elements which deflect the beam by 90.degree. with respect to the primary beam. A portion of the primary beam, striking the first deflecting element, passes through the element and is shifted slightly by refraction. This shift is compensated by a third beam deflecting element which is fully transmissive, and which refracts the stationary reference beam into alignment with the primary beam. By cutting the first and third deflection elements from the same sheet of material and reorienting the elements appropriately, slight deviation from parallelism in the opposing surfaces of the sheet of material are compensated.

  • Patent number: 4676597
    Abstract: The monochromator presents, in the plane of the slit (5), a mirror (6) which reflects the radiations comprised within the spectrum portion selected by the slit (5) towards the grating (3) dispersing a non-monochromatic beam. The radiations reflected recombine into a single, substantially monochromatic beam on the grating (3), and a suitable optical system (7,8) focuses such a beam forming the substantially monochromatic image of the source (1).

  • Patent number: 4674837
    Abstract: An apparatus produces complete stereoscopic images of a three-dimensional object. It comprises an image transmitter (13) on which are shown one after the other in time two-dimensional images (14) corresponding to sections lying one behind the other in space. In addition, the element (18) is provided which is disposed between the image transmitter (13) and an observer (36), said element being synchronously controlled by the image transmitter (13) and changing the spatial positioning of the image (14) between image transmitter (13) and observer (36). Optical means (31, 32) serve to reduce an image (14) shown on the image transmitter (13) in the plane of the element (18) and to re-enlarge it for analysis. The apparatus is particularly suitable for showing tomographic pictures, i.e. for imaging the inside of a living body.

  • Patent number: 4671628
    Abstract: In the image-side beam path of an objective lens are roof-like mirrors for pupil separation. The two beams pass to a mirror means where the two beams are directed on to an intermediate image plane by pivotal mirrors. The two optical axes cross in the intermediate image plane. In the region of the intermediate image plane is a field lens which feeds the beams to the eyes by way of a beam exit lens. That arrangement provides a stereoscopic image with large depth of focus. The exit pupils are larger than those of the eyes so that the viewer has a certain range of possible movement.

  • Patent number: 4671613
    Abstract: An improved geometry for an optical beam splitter prism permits all input and output beams to be parallel and to remain parallel while the prism is misaligned. It is particularly useful in conjunction with fiber optic couplers and is applicable to splitting with respect to light intensity, polarization or wavelength. This can be achieved through the construction of a beam splitting prism having an additional reflecting surface on one input beam and on one output beam, whereby each of these surfaces are parallel to the beam splitting surface and with two parallel input and output surfaces through which all beams pass so as to make all input and output beams parallel and remain parallel as the prism is translationally or rotationally misaligned about any axis.

  • Patent number: 4664475
    Abstract: A mounting and stowage mechanism erects a head-up display combiner into the pilot's line-of-sight. One end of a crank is mounted on the combiner and is pivoted on a first link which is pivoted to a frame. A support link is pivoted on the combiner and on a drag link which is pivoted to the frame. A connecting link is pivoted to both the first link and the outer pivot of the drag link to complete a compound 4-bar linkage which controls the path of the combiner between the erected position and a stowed position out of the pilot's line-of-sight. Manual control is through a handle which is mounted on a slider for linear motion and is connected to the end of the crank remote from the combiner. The mechanism is rendered insensitive to motion in the combiner-erect position by assuring that the instant centers of the links carrying the combiner are located at twice the focal length from the combiner along a line that runs through the center of curvature of the combiner and its focal point.
