Quotient of the luminous intensity reflected in the direction considered, divided by the illuminance at the retro-reflector for given angles of entrance, observation and rotation.
Note: In the photometry of retro-reflectors, this coefficient is designated by the abbreviation C.I.L. It is usually expressed in millicandelas per lux (mcd/lx).
Reference: C.I.E.
Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
