Heraeus Noblelight at PV show in Mailand in September 2007

Infrared Emitter with a New QRC Reflector
  • Infrared Emitters transfer large amounts of energy in a contact-free manner.
  • Infrared radiation is targeted by means of reflectors
  • Heraeus Noblelight is showing a new integrated reflector at the PV Expo in Mailand in September

Many sensitive heating processes run faster, more efficiently and somewhat more stable when infrared emitters with the new QRC reflector are used.



Infrared heat can be more effectively utilised by using reflectors. These save energy and valuable production space. A newly developed quartz reflector sits directly on the emitter and helps to ensure more efficient application of infrared radiation, both under vacuum and in high temperature processes.

Comprehensive tests at Heraeus, and also on site at the first users, show that the temperature stability of the new reflector ensures a uniform process. The new QRC (quartz reflective coating) reflector consists of high purity synthetic quartz material, with which the quartz glass tube is coated.

Heraeus Noblelight is showing infrared emitters with the new integral reflector at the “22nd European Photovoltaic Solar Energy Conference and Exhibition” in Mailand at the beginning of September.

Solar cells aim to make optimum use of solar energy. An anti-reflective coating provides for a significantly better absorption performance for solar cells. This coating is carried out in vacuum and at high temperatures.

It has been shown that such high temperature processes can be carried out in a significantly more stable fashion using infrared emitters featuring the new QRC reflectors, as process parameters such as temperature or the heating time can be better maintained. This increases the energy efficiency of a system.

Unlike other quartz reflectors, the QRC reflector is not an externally applied quartz shell but is a coating of synthetic quartz glass applied directly to the infrared emitter. As a result, the emitter is very compact and requires very little working space. With the QRC reflector, Heraeus Noblelight has succeeded in creating, for the first time, a reflector for vacuum applications which sits directly on the emitter.

The synthetic quartz material is of high purity and has a reflectivity which is not quite as effective as a gold coating but is better than a stainless steel reflector. The quartz reflector has very good heat resistance up to around 1000ºC and is also resistant to acids, lyes and other aggressive substances. Consequently, emitters with this reflector can be used even in manufacturing processes where the manufacturing plant requires regular cleaning with corrosive cleaning agents.

Visitors to the Heraeus stand at the PV exhibition in Mailand could see an infrared emitter with the new reflector of opaque quartz glass in operation. A module specially built for the exhibition demonstrated how the reflector allows heat to be focused directly onto the product and gave some indication of how energy can be saved with the improved process.

Infrared emitters are compact and transfer large amounts of energy without the need of a contact medium. This makes thermal processes in vacuum possible and helps in the efficient use of valuable production space. In contrast to metal tube emitters, which conventionally have often been used under vacuum conditions, infrared emitters from Heraeus Noblelight have a higher power density and are significantly more responsive. As a result, heating operations are performed faster and in a more controlled fashion.

Heraeus Noblelight GmbH, with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China, Australia and Puerto Rico, is one of the technology- and market-leaders in the production of specialist light sources.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
