UV LEDs below 400nm wavelength
Heat Curing is one application which utilizes UV wavelengths for polymerization but traditional sources which include Mercury lamps can damage the subject matter, are highly inefficient and use harmful materials for their operation. LEDs at wavelengths of 355nm to 400nm on the other hand are a highly efficient, longer lifetime alternative to standard bulb types. Temperatures are easily controllable with LEDs and the time needed to cure can be drastically reduced without damage to the scanned object. Custom packaging of UV die in LED or array configurations are also available.
UV LEDs are widely used in general sensing applications which include airport identification and inspection equipment, coin and bill validation and medical sensing and purification.
Marktech in 2011 will add additional wavelengths to the UV product offerings starting at 280nm. For status please contact our sales department.
