Thermo Riko's patented GVL infrared rapid heaters are using a specially designed Infrared Lamp to emit NIR wavelength. Gold coated spheroid reflectors are precisely manufactured to collect the NIR efficiently and introduce the infrared wavelength to the top of the Quartz rod. The Quartz rod transferes the NIR wavelength with minimal loss of wavelength towards the substrate surface. For more information for the technology, please visit Technology page
