CORONA Golden 8 infrared emitters are made of high-quality quartz tubes and feature a gold reflector for highest efficiency. Heraeus's unique twin-tube layout (the "Golden 8") gives the emitters a higher radiation density and improved mechanical stability. They are available as short-wave, medium-wave and fast medium-wave infrared emitters. This allows you to choose the optimal wavelength for the material to be heated. Dimensions and filaments are fabricated to meet your requirements.

CORONA IR emitters are also available for special geometries, e.g. omega-shaped, bent or as a complete IR system.
