    Abstract: An endoscope has a cannula, one and only one translucent or transparent cover at a distal end of the cannula, a light source and imaging system, both inside the cannula. The light source delivers light into the cover. At least some of that light passes through the cover to illuminate an inspection site inside the patient's body; some of that light is internally reflected at an outer surface of the cover to travel back toward an inner surface of the cover. The imaging system receives the light that has been reflected off the inspection site and returned to the endoscope through the cover. The components are configured such that none of the light that is internally reflected at the outer surface of the cover reaches an optical input of the imaging system directly (e.g., without being further reflected).

    Abstract: An inspection device for inspecting a panel, in particular a display, or a PCB, includes a first mirror, a second mirror, a third mirror, and a sensor. The first mirror, the second mirror, and the third mirror are arranged to display a section of the panel to be inspected on the sensor with a magnification factor greater than one. At least two of the group of the first mirror, the second mirror, and the third mirror, have both a first type of curvature, and a remaining mirror has a second type of curvature, opposite to the first type of curvature. The first mirror, the second mirror, and the third mirror form a telecentric system which is telecentric on a panel facing side and/or on a sensor facing side.

    Abstract: An endoscope system (100) for imaging a sample, an inner part of a patient, or an organ with an imaging device (150) includes an endoscope tube (130) with a proximal end and a distal end configured to mount the imaging device. A handle (120) at the endoscope tube proximal end is configured to move the endoscope tube rotationally. An interface (160) is configured to removably attach the endoscope tube to the handle and to rotate the endoscope tube around a main axis relative to the handle without restriction.

    Abstract: An optical projection assembly directs a first image to an eyebox of a user combined with light from a second source. A relay optic has a non-rotationally symmetric refractive gradient- index (GRIN) component arranged to receive the first image. A tilted, partially reflective combiner has a tilted first surface to receive and transmit the light from the second source, and an opposite second surface to receive and project the first image from the relay optic and transmit the light received from the second source to the eyebox. The GRIN component is configured to reduce a perceivable aberration of the first image introduced by the combiner.

    Abstract: An optical system providing reduced retroreflection includes an optical element with an optic aperture. A retroreflection defeat filter has a partially obstructing material configured to absorb or reflect a subset of the optical system waveband while transmitting the rest. The partially obstructing material is arranged to occupy a first portion of the optic aperture being at least half of the optic aperture, and the partially obstructing material does not occupy a second portion of the optic aperture for the remainder of the optic aperture.

    Abstract: An endoscope system (200, 300) for imaging an interior of a patient (180) comprises an endoscope tube (210, 310), an imaging unit (350) for imaging the interior of the patient, wherein the imaging unit is at least partially located inside the endoscope tube, and an optical coherence tomography unit (360), wherein said imaging unit (350) is distinct from the OCT unit (360), and wherein a sample arm (360c) of the OCT unit is at least partially located inside the endoscope tube.
