DOEs, MEMS and other microstructures replication
There are a number of techniques that can be used to replicate diffractive optical elements (DOEs), micro-electromechanical systems (MEMS, also referred to as micro-machines in Japan, or micro systems in Europe), and other surface relief microstructures. The popular methods include embossing, injection moulding and casting.
Generally speaking, casting is most suitable for high-quality and small quantities replication in laboratories. Injection moulding is a technique adapted from the well-established compact disks (CDs) production. It is the most popular replication technique in mass production. Embossing is a trade-off approach between injection moulding and casting.
Wuxi OptonTech Ltd uses hot embossing to replicate DOEs, MEMS and other surface microstructures. We offer very high precision replication services. Please contact us for details.
