Product description

This is a shield with a certain pattern engraved to selectively transmit light.

Using photomasks, many circuits and patterns can be formed.

Photomasks are used as a substrate for microcircuits used in semiconductor integrated circuits (LSI), flat panel displays (LCDs, OLEDs), and printed circuit boards (PCBs).
