The term "ultraviolet" means "beyond violet." In the visible part of the spectrum, wavelength decreases and the energy of the electromagnetic waves increases, so UV light has a shorter wavelength, and more energy than violet light. Wavelengths are measured in nanometers (nm), or billionths of a meter, and ultraviolet wavelengths range between 10nm and 400nm. It can be classified as UV-A, UV-B or UV-C, in order of decreasing wavelength.

Heraeus can manufacture Mercury Arc UV Lamps from a 12mm long up to a 3.9 metre long and everything in between. With over 8,000 lamp specifications on our database we can provide replacement UV lamps for any type of UV Curing equipment.The unique flexibility of our production line means we can make anything from just one replacement UV lamp for your system, up to large batch quantities for the most widely used types. Power ratings range from 80 watts per cm up to 400 watts per cm.


UV, or ultraviolet light is an invisible form of electromagnetic radiation that has a shorter wavelength than the light humans can see. It carries more energy than visible light and can sometimes break bonds between atoms and molecules, altering the chemistry of materials exposed to it. UV light can also cause some substances to emit visible light, a phenomenon known as fluorescence. This form of light — which is present in sunlight — can be beneficial to health, as it stimulates the production of vitamin D and can kill harmful microorganisms, but excessive exposure can cause sunburn and increase the risk of skin cancer.




The operating life of a UV curing lamp is measured in hours of ultra-violet output, which reduces gradually throughout the life of the lamp. Standard UV curing lamps emit enough UV to cure for 1000 hours. Improved production techniques and higher grade materials have enabled Heraeus Amba to produce UV lamps with operating life in excess of 1500 hours, when operated in suitable machines under optimum conditions.

200% tested for absolute reliability! Every Amba UV lamp is tested not once, but twice before it leaves our factory. This means no surprises when you install it; it starts first time, every time, so you have minimum down-time on your lamp changeovers.
