Heraeus noblelight is a provider of industrial heating processes. A heraeus heater is always matched to the process and not vice versa. For many applications, an infrared emitter consisting of just a heating element in a quartz tube is the perfect choice. Such emitters are, in the main, shorter than twin tubes. Obviously, round tube emitters can also be fitted with a gold reflector. The halogen short wave [nir] radiation is provided by halogen infrared emitters, with a spectrum in the near infrared region, a maximum power density of 1 mw per square metre and very fast response times. These emitters are manufactured in top quality quartz glass and are conventionally round tubes. Optional gold reflectors can virtually double the amount of effective radiation drop out on the product.
