Provided is an optical sensor see-through window condensation preventing apparatus to prevent a see-through window where light penetrates from having condensation. The optical sensor see-through window condensation preventing apparatus includes: a pipe installed on one side of a heating furnace of an annealing simulation device and where the see-through window, where the light of an optical sensor penetrates, is installed in a front end; a covering installed in the front end of the pipe and fixating the see-through window; and a communication pipe of which one end is connected to a side surface of the pipe to be communicate with the inside of the heating furnace and of which the other end is extended toward an outer surface of the see-through window to supply a high-temperature gas in the heating furnace to the outer surface of the see-through window. |
