Product description

This is a shield with an engraved pattern that selectively transmits light.

Several circuits and patterns can be formed using photo masks.

Photo masks are used as a substrate for microcircuits during the production of semiconductor integrated circuits (LSI), flat panel displays (LCDs, OLEDs), and printed circuit boards (PCBs).
