http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/polabs.html A dichroic filter, thin-film filter, or interference filter is a color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, dichroic mirrors and dichroic reflectors tend to be characterized by the colors of light that they reflect, rather than the colors they pass. Dichroic filters can filter light from a white light source to produce light that is pe… propose new meeting time in outlook calendarWebNot before centuries later this dichroic effect was explained. It was in 1990 using transmission electron microscopy when it was discovered that the cup's glass contained gold and silver alloy colloids [34].
