摘要： A video measurement system includes an imaging system, a reticle projector for projecting an image of a reticle through the imaging system onto the test object, and a camera for capturing images of the test object together with the reticle image projected onto the test object through the imaging system. A selective reflector reflects the reticle image into the camera from a position along the imaging system in advance of the test object. A mode selector is operable in a first mode for directing the reticle image to the test object and from the test object to the camera and is operable in a second mode for directing the reticle image to the selective reflector and from the selective reflector to the camera.

摘要： A probe for an optical measurement system includes a probe body arranged to be adjustably mounted in a measuring machine for optically measuring a test object. A single mode fiber optically coupled within the probe body transmits a source beam having an instantaneous or sequentially established bandwidth spanning a range of wavelengths to the probe body and also transmits a measurement beam from the probe body toward a detector. An adjustable beam manipulator within the probe body spatially excludes portions of the reference beam over a progression of different size portions from being focused within the acceptance cone of the single mode fiber to more closely balance the intensities of the reflected object beam and the reflected reference beam within the measurement beam.

摘要： An optical measurement system includes an optical sensor assembly for measuring an object located beneath the optical sensor assembly. A deployment mechanism is pivotally connected relative to the optical sensor assembly that moves a secondary measurement aid, such as a touch sensor, between a deployed position and a retracted position. When in the retracted position, the secondary measurement aid does not inhibit movement of the optical sensor with respect to the object being measured.

摘要： A process for pre-calibrating illumination sources permits illumination light intensities to be set to a near optimal level during training of an optical inspection system. Applicants have found that the illumination source intensities for a category of illuminators are sufficiently constant from machine to machine that the data collected during calibration of an illumination source on a machine using a particular type of source may be used on other machines of the same type using the same type of illumination source when combined with the reticle light intensity data for different zoom magnification's of the particular machine being used. That is, using known data for particular machine and the illumination source light intensity data for the same type of machine and illumination source permits accurate presetting of an illumination source.

摘要： An optical comparator arranged for rear projection onto a viewing screen combines an optical projector that projects an optical image of a test part under inspection onto the viewing screen with a video projector that projects an optical image of a pixilated template pattern containing illustrated specifications of the test part onto the same viewing screen. The images of the test part and the pixilated template pattern are projected concurrently onto the viewing screen for visually comparing the form of the test part against its specified form.

摘要： An illumination system shares portions of an objective of an optical inspection system. A plurality of beam-shaping optics collects light from a plurality of effective light sources and directs the light through a portion of the objective for illuminating an object under inspection. The objective includes a front relay lens, a rear relay lens, and an objective stop disposed between the front and rear relay lenses for collecting light scattered from the object and forming an image of the object with the collected light. The beam-shaping optics, which surround the objective stop, are arranged together with the associated effective light sources for non-uniformly distributing light within a range of angles required for illuminating the object.

摘要： An actuator for selectively extending and retracting a probe in a measuring instrument comprises an actuator body, a carriage having a first aperture slidably attached to the body, and a second aperture receiving a probe holder having a probe. The first aperture of the carriage, which surrounds the actuator body, includes a first plurality of magnets disposed around an inner circumference of the aperture. The actuator body includes a lead screw, a round lead screw nut mated with the lead screw, and a second plurality of magnets arranged on a periphery of the lead screw nut, generally aligned with the first plurality of magnets. The magnets are arranged so that the carriage may be displaced with respect to the actuator body a sufficient amount that the magnets do not significantly restrain the further movement of the carriage.

摘要： This high performance front objective lens system intended primarily for use with a video inspection apparatus has a first lens set in the form of a doublet, with a second lens set intermediate the first lens set and the imaging plane. The second lens set includes a doublet and an adjacent lens. The overall system has an effective focal length of 50 mm, a front focal length of 38.75 mm, and a numerical aperture greater than 0.2. Further, the material of the doublets is chosen to have a small, gradual transition in index between the elements of the lens and the cement, minimizing back reflections and thereby eliminating the need for index matching coatings on the cemented surfaces of the doublets. Finally, the imaging plane of the system matches that of standard ring lights used with video inspection apparatus.
