Optoelectronics Optoelectronics is at the heart of world's $1.5 trillion information industry. Compugraphics supplies photomasks to key optoelectronics manufacturers. Like MEMS, this fast-moving, exciting sector depends on absolute accuracy, quality and cost-effectiveness in the photomasks we supply. Also like MEMS, optoelectronics sets us a unique set of challenges and criteria. We have been working with some of the biggest names in the sector from the very start. This has allowed us to shape specific technical solutions to specific optoelectronic product challenges.
