  • Patent number: 5754335
    Abstract: Before a measurement for an infrared analysis of a sample is performed, a measurement area of the sample is set. In the measurement area setting mode, a camera takes the image of the whole sample, and the image is shown on a display. An image of an aperture is superimposed on the image of the sample in the display. When an operator uses a mouse connected to a controller of the infrared microscope to change the width of the image of the aperture on the display, an aperture signal generator generates an aperture signal corresponding to the width of the aperture image. An aperture image signal generator receives the aperture signal and generates an aperture image signal having the width. Thus the image of the sample superimposed on the image of the aperture in the display changes accordingly, by which the operator confirms the measurement area, i.e., the position and width of the aperture, in the sample.

  • Patent number: 5640270
    Abstract: A broad-bandwidth interferometric device is adapted for longitudinal insertion into a cylinder cavity to produce irradiance signals at multiple vertical-scanning positions as a function of optical path differences between a reference mirror incorporated in the probe and the cylinder-wall surface. The light-source beam is passed through an objective lens placed longitudinally in the cylinder and then divided by a beam splitter disposed in fixed relation to the cylinder wall to produce a test beam directed radially to the wall and a reference beam directed axially to a reference mirror disposed in fixed relation to the lens. During scanning, the objective lens and reference mirror are translated together, while the beam splitter remains stationary with respect to the cylinder wall, thereby varying the position of the focal point of the test beam and providing the vertical-scanning effect required to produce interference fringes and a corresponding map of the tested cylinder surface.

  • Patent number: 5481401
    Abstract: Light from a mercury lamp is focused by an objective lens system and is incident on a specimen to be examined. A focusing optical path of light reflected by the specimen is split into an optical path of an ultraviolet ray and an optical path of visible light by a dichroic mirror having wavelength selectivity. The ultraviolet ray is guided to an ultraviolet CCD camera. The ultraviolet CCD camera supplies a monochrome picture signal to a monochrome display through a first picture processor. On the other hand, the visible light is guided to a color CCD camera. The color CCD camera supplies a color picture signal to a color display through a second picture processor. Therefore, an ultraviolet picture of the specimen is displayed on the monochrome display at a high resolving power and a large magnification. At the same time, a color picture of the specimen is displayed on the color display.

  • Patent number: 5355252
    Abstract: A scanning laser microscope capable of detecting a fine structure producing low contrast and easily measuring the length, the volume, and so forth of an object. A laser beam is focused onto the object. The beam is scanned at regular intervals, or in a digital fashion, in two dimensions. Light scattered from the object is detected by a detector to observe an image of the object. The output signal from the detector is digitized into a given number of gray levels in synchronism with the digital scans. The object image can be stored in a memory and processed while correlating the scanned position with the intensity of the scattered light at this position.

  • Patent number: 5307098
    Abstract: A projection inspector which projects the image of an object being measured onto a screen for a visual inspection. It may be used with a microscope for observation in detail. Unlike the conventional projection inspector, the inspector fully exhibits high degree of measuring function even at the time of inspecting an object having a surface color and shape that can be difficultly imaged, and projects the object's image onto the screen to inspect it, and further enables the object's image to be more correctly observed or inspected using a microscope.

  • Patent number: 5134515
    Abstract: The housing (10), which is inserted between the magnification selector (7) and the ocular tube (8) of a microscope, accommodates a pivotable mirror (22) which is normally placed outside the beam path of the microscope, but which by actuating a lever (17) can be pivoted into the beam path in order to deliver the latter through a photo cone (13) to a camera (14). By actuating the lever (17), the camera (14) is released after the required chronological delay in order to take a picture of the object, e.g. an eye (4). A diaphragm arrangement, which can be brought into the preselected position for the exposure as well by actuation of the lever (17), is disposed at the entry of the housing (10), i.e. directly adjacent the magnification selector (7). Due to the full availability of the light and the advantageous position and adjustability of the diaphragm, optimum conditions exist both for observation and for photographical exposures.
