UV LED Curing equipment [4] Low-pressure mercury-vapor lamps generate primarily 254 nm 'UVC' energy, and are most commonly used in disinfection applications. Operated at lower temperatures and with less voltage than medium-pressure lamps, they, like all UV sources , require shielding when operated to prevent excess exposure of skin and eyes.
The next type of curing light developed was the quartz-halogen bulb; [4] this device had longer wavelengths of the visible light spectrum and allowed for greater penetration of the curing light and light energy for resin composites. [3] The halogen curing light replaced the UV curing light. The 1990s presented great improvements in light curing ...
Photonic curing of a printed nanosilver trace on PET.. Photonic curing is the high-temperature thermal processing of a thin film using pulsed light from a flashlamp. [1] When this transient processing is done on a low-temperature substrate such as plastic or paper, it is possible to attain a significantly higher temperature than the substrate [2] can ordinarily withstand under an equilibrium ...
Extreme ultraviolet lithography (EUVL, also known simply as EUV) is a technology used in the semiconductor industry for manufacturing integrated circuits (ICs). It is a type of photolithography that uses 13.5 nm extreme ultraviolet (EUV) light from a laser-pulsed tin (Sn) plasma to create intricate patterns on semiconductor substrates.
UV can be applied on spot locations of the paper or by flooding the page. This coating application can deepen the color of the printed area. Drying is virtually instantaneous when exposed to the correct level of UV light so projects can move quickly into the bindery.
Low power consumption of semiconductors introduce UV disinfection systems that utilized small solar cells in remote or Third World applications. [2] By 2019, LEDs made up 41.4% of UV light sales, up from 19.2% in 2014 [3] The UV-C LED global market is expected to rise from $223m in 2017 to US$991m in 2023. [4]

There are four UVB types of lamps: Fluorescnt Broad-Band UVB that emit 280-330 nanometer, Fluorescent Narrow-Band that emit 312 nanometer, Excimer that emit 308 nanometer and LED that emit 290-300 nanometer. PUVA means UVA + psoralen. It consists of irradiation of the skin with the UVA ultraviolet light, from a fluorescent bulb or LED lamps.
