  • Patent number: 11051698
    Abstract: An optical microscopy probe for scanning microscopy imaging of object has a housing with an optical window at a side position at the distal end of the housing, and an optical guide having an objective lens rigidly coupled to an end portion of the optical guide. The optical guide is displaceably mounted in a transverse direction of the housing so as to enable optical scanning in a region of interest. A relay lens unit is rigidly mounted at the distal end of the probe and it has a first lens, a second lens and a mirror. The relay lens unit is optically arranged relative to the objective lens for allowing scanning microscopy through the optical window at the side of the distal end of the housing.

  • Publication number: 20140316282
    Abstract: The present invention discloses an optical microscopy probe (10) for scanning microscopy imaging of object (O). The probe has an optical window (22), and an optical guide (2) having an objective lens (6) rigidly coupled to an end portion of the optical guide. The optical guide is displaceably mounted in a transverse direction of the housing (21) so as to enable optical scanning in a region of interest (ROI). A relay lens unit (25) is rigidly mounted at the distal end (23) of the probe and it has a first lens (25a), a second lens (25b) and a mirror (25c), the relay lens unit being optically arranged relative to the objective lens for allowing scanning microscopy through the optical window of the housing. The invention is advantageous for obtaining an improvement in the available field of view of the probe because the cooperation between the displaceable objective lens and the relay lens unit may compensate for the relative limited free working distance of the objective lens.

  • Publication number: 20070067781
    Abstract: A disk drive unit having a disk loading mechanism, for use in a mobile device. The loading mechanism is arranged for receiving a disk (A) through an opening in a housing of the device and bringing it into engagement with the disk drive, and vice versa. It comprises a tray (8) which is movable with respect to the housing and the disk drive between a first position for receiving a disk and a second position covering the opening and allowing the disk drive to engage the disk. The tray is rotatable about an axis (10) which substantially coincides with the drive axis (11) when in its driving position. This arrangement results in a slot loader having a tray which will hardly project outside the housing, resulting in a robust loading mechanism.
