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 ...
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.
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 ...
The differentiating factor of this process from others is the separation of the melt stage before the cure stage. UV-cured powder will melt in 60 to 120 seconds when reaching a temperature 110 °C and 130 °C. Once the melted coating is in this temperature window, it is instantly cured when exposed to UV light.

Oscilloscope OL-1 from 1954, the company's first with a relatively small 3-inch CRT which allowed for a highly competitive price of US$ 29.50 (equivalent to $345 in 2024) for the DIY kit. [1] Heathkit is the brand name of kits and other electronic products produced and marketed by the Heath Company.
