In addition to the exciton lines, there are surprisingly strong additional absorption lines in the same spectral region.
12.
One recently developed, novel source of broad spectrum radiation is synchrotron radiation which covers all of these spectral regions.
13.
Hyperspectral imaging is gaining importance in the applied spectroscopy particularly in the fields of NIR, SWIR, MWIR, and LWIR spectral regions.
14.
PEB and DBV bilins in PE545 absorb in the green spectral region too, with maxima at 545 and 569 nm respectively.
15.
This was later extended to other spectral regions by Klemperer and many others, and has qualitatively changed the questions that could be asked.
16.
Lead sulphide ( PbS ) and indium antimonide ( InSb ) LDRs ( light-dependent resistors ) are used for the mid-infrared spectral region.
17.
In these spectral regions the atmospheric gases ( mainly water and CO 2 ) present low absorption and allow infrared viewing over kilometer distances.
18.
Still, much of the reported research and applications, utilizing the photoacoustic effect, is concerned with the near ultraviolet / visible and infrared spectral regions.
19.
A secondary focus of research is based on the component development for the far-infrared spectral region, the so-called excitation which allow for active control.
20.
The moderately bright R-type asteroid has a surface that strongly absorbs in the olivine and pyroxene spectral region, which give it its very reddish color.
