Dichroic Black Rod.
5 - 6 mm Moretti rods, each 16" (406mm) long. Approximately one-third of the rod surface [1/2" (25mm) on each side] is subjected to a metallic thin film deposition (spot where it is held in the coating chamber is not coated). Coated surface should be kept away from the flame and quickly encased with clear glass.
