Replicated Mirrors

Our precision optical replication production has exceeded 1,000 finished components per day, providing our customers an affordable and reliable supply of diffractive, transmissive, and reflective optical components which require high surface figure accuracy, nanometer range surface feature duplication, and low RMS surface roughness at a fraction of the original master surface production cost.
