1. The majority of spectrophotometers are used in spectral regions near the visible spectrum. 2. This information is then converted into a black-and-white picture corresponding to each spectral region . 3. The Sm ion is a potential UV-A to blue spectral region hinders commercial application. 4. Thus, it is possible to construct radiation sources with high intensity within certain narrow spectral regions . 5. Astro-2 was the second dedicated Spacelab mission to conduct astronomical observations in the ultraviolet spectral regions . 6. Furthermore, there is very little solar or other natural background radiation in the microwave spectral region . 7. The attenuation will rapidly increase outside this spectral region because of absorption in the glass substrate. 8. ARSS is additionally equipped with a UV-MFR instrument for radiation measurements in the UV spectral region . 9. The type of sample container used must allow radiation to pass over the spectral region of interest. 10. It is related to the brightness, which is the luminosity of an object in a given spectral region .
