In order to produce on the table of a diamond gemstone (7), an information mark which is invisible to the naked eye using a x10 loupe, an ultraviolet laser (1) having a wavelength of 193 nm is used in association with a mask (2) to irradiate the surface of the stone (7) at a fluence of less than 2 J / cm2 per pulse and with not fewer than 100 pulses, in the presence of air which reacts with the diamond (7) and causes the mark to be formed without any darkening which is visible when viewing using a microscope.

A image magnifier for the vision impaired which magnifies the image of face up source material (13) placed in the visual field of the camera (15) and displays the magnified image on a display (20). One embodiment includes a static high-resolution image mode and a second live video mode. The controller (29) provides different lighting appropriate for each mode. In a further embodiment the magnifier is transportable. Each part (17, 14, 16) is hinged (18, 19) to the other parts (17, 14, 16) allowing it to be folded into a compact lightweight form to be portably carried. In a still further embodiment the magnifier includes shielding for the lighting to minimise or avoid specular reflections.

A method and an apparatus for laser marking indicia in the volume of gemstones such as diamonds, the indicia being made up of a plurality of microscopic dot-shaped marks whose build-up can be initiated by exposing naturally-occurring internal defects or impurities in the volume of a gemstone to a tightly focused train of laser pulses. Authentication data is encoded in the gemstone from the relative spatial arrangement of the dot-shaped marks that form the indicium. Taking advantage of the presence of otherwise invisible defects in the gemstone allows for inscribing indicia with laser pulses carrying energies substantially lower than the threshold energy required for inscribing in the volume of a perfect gemstone material. The marking process is then much less susceptible to inflict damages to the surface of the gemstone, and the marking can be performed using a broad variety of femtosecond laser systems. The dot-shaped marks engraved at a depth below the surface of a gemstone can be made undetectable with the unaided eye or with a loupe by limiting their individual size to a few micrometers, while devising indicia made up of only a few marks. As a result, the marking does not detract from the appearance and value of the gemstone. The procedure for laser marking accounts for the random spatial distribution of the defects present in natural gemstones as well as for their strongly localized character. The presence of an indicium can be detected by using a dedicated optical reader that can be afforded by every jewellery store.

Video frame loupes are presented that provide a frame-by-frame video navigation tool. A video frame loupe is a graphical user interface (UI) element that may be displayed over a portion of a display screen, and which may be used by a user to navigate frames of a video clip. For example, a user may provider a user input to activate the video frame loupe to be displayed as a preview window that presents a continuum of frames available at the time corresponding to a point at which the video frame loupe UI was invoked. The user may then navigate forward / backward with frame-level accuracy.

A magnifying spot mirror releasably attachable to a flat surface includes a circular concave mirror plate mounted on the front surface of a lenticular-shaped support body which has a convex, arcuately curved rear surface from which protrude satellite suction cups that have circular bases which lie in a convex plane and are radially spaced equidistant from the center of the support body and an optional center suction cup. Applying finger pressure to the center of the mirror causes a pair of centrally located suction cups and / or the optional center cup to hermetically grip a flat surface with the mirror parallel to the surface. Pressing on the mirror at a location offset from the center exerts a tensional unsealing force on radially inwardly located suction cups, and compressional sealing forces on outer satellite suction cups, thus re-positioning the mirror at a different orientation angle.

A magnification loupe carried by spectacles has a Galilean lens system comprising a single-element eyepiece lens and a two-element objective lens. The loupes may be mounted to eyeglass frames by a flip-up mounting member, or they may be mounted through the eyeglass lenses of the spectacles.

A loupe and lighting assembly for enhancing detection of dust particles on the optical sensor of a digital camera. The assembly is made of a cylindroid hollow-centered main frame body, into which is fixed a loupe lens. A battery housing is joined to the body in order to supply electrical power to a LED array. The LED array is made from a plurality of LED diodes mounted peripherally and around the inside of the cylindroid body, being tilted at an acute angle from the axis orthogonal to the plane of the cylindroid body so that all diodes axially converge toward a single focal point, at a certain distance from the main frame body. The dust particles scattered upon the sensor become clearly visible to an observer looking through the assembly when the dust particles location coincide with the LED common focal point.
