This guy is supposed to be sensitive to circular polarized light throughout the entire visible region.
They operate almost like spectrophotometers in the visible region.
This is light ranging from the far infrared through the visible and on into the near X-ray region.
Space probes made it possible to collect data from not only the visible light region, but in other areas of the electromagnetic spectrum.
At the time of its closest approach on 8 January 2003 it had an apparent brightness in the visible region of magnitude 20.4.
Instead, they switch applications by clicking on visible regions of windows.
Thus, in the visible region of the spectrum, only superficial assessment of tissue features is possible.
The sun, at 5000 degrees, has a peak around 0.5 eV, or slightly below the visible region.
It tails off onto the visible region and is responsible for the intrinsic blue color of water.
It is one of the most intense regions of stellar formation visible in our galaxy.
