Year of the Peridoic Table


What does the periodic table have to do with Infrared emitters, UV- or Flash technology?
Lots of elements contribute in giving these systems and emitters the incredible power to make light technically usable.

Many of us know the periodic table from school. It represents the chemical elements in an order system. 150 years ago the periodic table was discovered independently by the chemists Dimitri Mendelejew and Lothar Meyer. Therefore, the United Nations and UNESCO declared 2019 as the International Year of Periodic Table.

H - Hydrogen

Hydrogen is the most common element in the universe. Deuterium, a natural isotope of hydrogen, is a very important element for Excelitas Noblelight.
Due to its mass it is also known as "heavy hydrogen". Excelitas Noblelight manufactures deuterium lamps that are the ideal light source for high-precision absorption measurements in the laboratory by generating a continuous spectrum with wavelengths ranging from UV to visible light. Thus, they help determine traces of undesired contamination such as melamine in milk powder for babies.

C - Carbon

Noblelight carbon infrared emitters feature a unique design of the heating filament that combines the efficient radiation with very short response times.

This accelerates the heat process while at the same time achieving high efficiency.

To be found in these products:

Si - Silicon

Most Noblelight emitters are made from high-purity fused silica which ensures transmission and thermal stability.

Fused silica is extremely resistant against heat, acids, alkalis and other aggressive substances.

Xe - Xenon

Xenon is a noble gas found in small amounts in the Earth’s atmosphere. It was discovered in 1898 by the chemists William Ramsay and Morris Travers. The name “xenon” was inspired by the Greek word for “stranger”.

Excelitas Noblelight used Xenon for example in xenon flash lamps, which can be used, for example, to check production quality of solar cells and solar modules and to characterise the cells and assign them to power classes. Only cells that are optimally compatible with each other are combined to form a module. This requires reliable and reproducible light sources which have a spectrum that comes as close as possible to that of the sun. Xenon flash lamps, small and ring-shaped or linear and up to two meters long, are suitable light sources.

Ta - Tantalum

Tantalum is a rare, hard, shiny transition metal with high corrosion resistance. It forms the basis for a protective oxide layer on components. Tantalum ensures a long service life in infrared emitters, for example as a disc on the heating filament.

To be found in these products:

Au- Gold

Excelitas Noblelight manufactures infrared emitters with a gold reflector that allows directed emission of heat to the product. A gold coating on the infrared emitters reflects the IR radiation. This almost doubles the efficient radiation onto the product.

To be found in these products:

Ar - Argon

Argon is a noble gas that makes up 0.93% of the earth’s atmosphere. It was discovered by William Ramsay and Lord Rayleigh in 1894. It is obtained from the air as a byproduct of the production of oxygen and nitrogen. It is often used in UV lamps as a filling gas.
