Answer 1

Vision Research is a broad field of science that deals with understanding vision in every aspect from the optics to the neuroscience.  One aspect of vision research is to understand the chemistry that occurs during the process of vision.  This necessitates studying photoreceptors and visual pigments of all types of animals under different lighting conditions.  Since many of the material that is studied is extremely small, specialized microspectrophotometers have been built to analyze them.
