11. Far infrared is often defined as any radiation with a wavelength of 15 CIE IR-B and IR-C bands.12. Hauser said the study shows that about 30 percent of the energy from starlight is present in the far infrared . 13. Spectrometers may also work operate over a wide range of non-optical wavelengths, from gamma rays and X-rays into the far infrared . 14. It has a wider transmission range than the more common potassium bromide beamsplitters, extending its working range into the far infrared . 15. It lies between the super high frequency band, and the far infrared band which is also referred to as the terahertz gap. 16. A dry powder fire extinguisher is said to be a good improvised system for production of aerosol effective even in far infrared . 17. The p-Ge ( p-type germanium ) laser is a tunable, solid state, far infrared laser which has existed for over 25 years. 18. Hauser said the instrument gathered measurements in the " far infrared , " a part of the electromagnetic spectrum invisible to the eye. 19. Megamaser hosts are rich in dust, which re-radiates in the far infrared and produces the high L FIR observed in hydroxyl megamaser hosts. 20. The main exception to this is shiny metal surfaces, which have low emissivities both in the visible wavelengths and in the far infrared .
