QRCInfrared Emitters With Nano-Reflector

SHARE

In contrast to conventional reflectors, the new nano-reflector is not made of gold or metal oxides but of opaque quartz glass. Quartz glass is extremely resistant to heat, acid, alkaline solutions and corroding substances. A gold coating on infrared emitters reflects the radiation very well - effective radiation onto the product is almost doubled. Measurements show that the reflectivity of opaque quartz material is about 60% to 70%. This is less than that of gold but comparable to a high-gloss polished aluminium reflector. However, an aluminium reflector will gradually lose its reflectivity as aluminium oxide is forming on its surface. Such oxides do not form on quartz glass.

The new reflector is located directly on the emitter and therefore needs not be brought into the correct position first as is the case with external reflectors.

Contoured QRC emitters
The QRC infrared emitter is continuously being developed further. A new development involves QRC emitters that can be precisely shaped to the contours of a product. In this way, the heat is guided directly to edges, burrs or corners - ideal for deburring or welding of three-dimensional plastic products.

Typical applications fields:
  • Coating under vacuum conditions
  • Coating of solar cells
  • In extrem surroundings
