A laser glass sculpture of a caffeine molecule. A bubblegram (also known as laser crystal, Subsurface Laser Engraving, 3D crystal engraving or vitrography) is a solid block of glass or transparent plastic that has been exposed to laser beams to generate three-dimensional designs inside.
Leptat glass is a glass that has been etched using a patented acid process. Leptat takes its name from the Czech word meaning "to etch", because the technique was inspired by a Bohemian, Czech Republic (former Czechoslovakian) glass exhibit viewed at a past World's Fair in Osaka, Japan, and patented in the United States by Bernard E. Gruenke ...
5D optical data storage (also branded as Superman memory crystal, [1] a reference to the Kryptonian memory crystals from the Superman franchise) is an experimental nanostructured glass for permanently recording digital data using a femtosecond laser writing process. [2]
The sensor or glass surfaces of the lens are clouded by the fungal attack and lens coatings may be etched away. The fungus can range from small, barely visible points to an irregularly spreading mesh, to complete "blindness" of the optics. [1] Example of an image from a camera with fungus in the low pass filter glass.
Magnified to 40x and 100x A wine glass with a laser-engraved fill line. Stone and glass do not vaporise or melt easily. As a result, this makes them generally a better candidate for other means of engraving, most notably sandblasting or cutting using diamonds and water. However, when a laser hits glass or stone, it fractures.
Beaker with soldier and civilian shaking hands, Bohemian glass, later 19th century. Engraved glass is a type of decorated glass that involves shallowly engraving the surface of a glass object, either by holding it against a rotating wheel, or manipulating a "diamond point" in the style of an engraving burin.
Areas of the photo-etch image may be stopped-out before etching to exclude them from the final image on the plate, or removed or lightened by scraping and burnishing once the plate has been etched. Once the photo-etching process is complete, the plate can be worked further as a normal intaglio plate, using drypoint, further etching, engraving ...
A laser printer uses a laser because lasers are able to form highly focused, precise, and intense beams of light, especially over the short distances inside of a printer. The laser is aimed at a rotating polygonal mirror which directs the light beam through a system of lenses and mirrors onto the photoreceptor drum, writing pixels at rates up ...
