Abstract: Filter wheel assemblies with a single actuation point to control positioning of front and rear optical filter elements simultaneously and to provide high channel density with a plurality of selectable optical filter pairs. A filter wheel assembly may include a plurality of optical filter element pairs arranged around a common axis, wherein each of the plurality of optical filter element pairs includes a first filter element and a complementary filter element, wherein each first filter element and each complementary filter element has a surface having a normal component directed toward an inner portion of the filter wheel assembly.
