Photolithography For the same process applied to metal, see Photochemical machining. Photolithography, also termed optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate.It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical  photoresist , or simply resist, on the substrate.or the same process applied to metal, see Photochemical machining.

- Photovoltaics (PV) is the name of a method of converting solar energy into direct current electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon commonly studied in physics, photochemistry and electrochemistry.he direct conversion of sunlight to electricity occurs without any moving parts or environmental emissions during operation. It is well proven, as photovoltaic systems have now been used for fifty years in specialized applications, and grid-connected PV systems have been in use for over twenty years.

T ips for determining when a U.S. postcard was published Photochromes are not real photos but rather, lithographed cards done by a photochrome process. To distinguish a printed post card from a real photo post card, examine it under a magnifying glass and you will see the dot pattern that is characteristic of lithographed cards. The best printed cards were produced by the photogravure process.

Lithography As a printing technology, lithography is different from intaglio printing (gravure), wherein a plate is either engraved, etched, or stippled to score cavities to contain the printing ink; and woodblock printing or letterpress printing, wherein ink is applied to the raised surfaces of letters or images.ithography works because of the mutual repulsion of oil and water. The image is drawn on the surface of the print plate with a fat or oil-based medium (hydrophobic) such as a wax crayon, which may be pigmented to make the drawing visible.

- A lithography is not a reproduction of a famous painting or work of art. They are the artist´s art work that was meant to be printed in that process and produced in a limited number, the more limited the number produced the more valuable(of course the artist´s cache also counts).op 10 facts about the world. A lithograph is a type of printing process during which original works of art can be printed and reproduced; the final product is also known as a lithograph, which is an authorized copy of an original work created by an artist or other skilled craftsmen.

Photorealism John Baeder, oil on canvas, 30×48 inches. Photorealism is a genre of art that encompasses painting, drawing and other graphic media, in which an artist studies a photograph and then attempts to reproduce the image as realistically as possible in another medium.lthough the term can be used broadly to describe artworks in many different media, it is also used to refer specifically to a group of paintings and painters of the United States art movement that began in the late 1960s and early 1970s.

Photodiode Theory of Operation Photodiode Theory of Operation. A silicon photodiode is a solid-state device which converts incident light into an electric current. It consists of a shallow diffused p-n junction, normally a p-on-n configuration although “P-type” devices (n-on-p) are available for enhanced responsivity in the 1µm region.

Photomorphogenesis (October 2007) In developmental biology, photomorphogenesis is light-mediated development, where plant growth patterns respond to the light spectrum. This is a completely separate process from photosynthesis where light is used as a source of energy.

What is Lithography? Lithography refers to a lithograph print that is made from an image which has been applied to a flat surface.It is a method of printing based on the principle that oil and water do not mix. Printing is done from a stone (lithographic limestone) or a metal plate with a grained surface; using oil based inks.ithography refers to a lithograph print that is made from an image which has been applied to a flat surface.

Holography In its pure form, holography requires the use of laser light for illuminating the subject and for viewing the finished hologram. In a side-by-side comparison under optimal conditions, a holographic image is visually indistinguishable from the actual subject, if the hologram and the subject are lit just as they were at the time of recording. A microscopic level of detail throughout the recorded volume of space can be reproduced.

- Polarized light is a concentration of light waves moving in the same direction and along the same plane. Light is like a wave that vibrates in many directions—it can vibrate from side to side or up and down. Polarized glare is caused by light waves vibrating horizontally. It can cause eye fatigue, headaches, or temporary blindness, which can lead to collisions or injuries.

offset printing (offset lithography) Offset printing, also called offset lithography, is a method of mass-production printing in which the images on metal plates are transferred (offset) to rubber blankets or rollers and then to the print media. The print media, usually paper, does not come into direct contact with the metal plates.

photolithography Photolithography is the standard method of printed circuit board (PCB) and microprocessor fabrication. The process uses light to make the conductive paths of a PCB layer and the paths and electronic components in the silicon wafer of microprocessors. The photolithography process involves light exposure through a mask to project the image of a circuit, much like a negative image in standard photography. This process hardens a photo-resistive layer on the PCB or wafer. The hardened areas stay behind in the form of circuit paths of PCBs and CPUs.
