  • Patent number: 8523457
    Abstract: An optical-fiber connector includes an insulative main body having a pair of optical components extending forwardly therefrom. Each optical component defines at least one lens and a guiding post located at outside of the lens. Each guiding post defines a through hole extend through the guiding post and the main body in a front-to-back direction and fulfilled with the air for transmitting a test light. The test light from the through hole of the guiding post acts as an accurate measuring reference of the true position between the lens and the fiber because of having no displacement of the light path through a through hole.
    Type: Grant

  • Patent number: 8430574
    Abstract: An optical fiber connector includes a mating portion defining a coupled direction and including pairs of lenses and a pair of guiding portions. The pair of guiding portions each defines a guiding hole through a front face thereof in the coupled direction. Each guiding hole has a cross section of a polygon shape in the coupled direction and is configured with an imaginary circle perpendicular to the coupled direction.

  • Patent number: 7532334
    Abstract: A heat deflection testing equipment (10) for measuring tolerance of a sample (60) includes a temperature controlling case (30) and an optical sensor (20). The case includes a base (40) and a cover (50). The case has a carrier (41) defining a convective chamber (42) and a partition (44). The partition and the cover jointly define a heating chamber (49). An exhaust hole (440) communicating with the heating chamber and the convective chamber is on the partition. A sample carrier (46) has a datum plane (462). A number of air tubes (48) are set around the sample carrier with openings facing the sample. Incident beams (200, 202, 204) from the sensor are projected on the datum plane and the sample. Reflex beams (201, 203, 205) are reflected from the datum plane and the sample. The geometric tolerance can be measured by analyzing the incident beams and the reflex beams.

  • Publication number: 20070070359
    Abstract: A heating geometric measure equipment (10) for measuring geometric tolerance of a sample (60) under heating atmosphere. The measure equipment (10) includes a temperature controlling case (30) and an optical sensor (20). The case (30) includes a base (40) and a cover (50) having a window (500) clipped on the case (30). The case (30) has a supporting section (41) defining a convective chamber therein and a partition (44) on the supporting section (41). The partition (44) and the cover (50) jointly define a heating chamber (49). A vent (402) communicating with the heating chamber (49) and the convective chamber (42) is defined on the partition (400). A sample carrier (46) having a datum plane (462) on an upper surface thereof is provided above the vent (402). A number of air tubes (48) are set around the sample carrier (46) with openings facing the sample carrier (46). The sensor (20) is horizontally movable above the cover (60) of the case (30).
