Omega Optical is pleased to announce the recent acquisition of Rugate Technologies, Inc., a research and development company focused on the design, process development, and manufacturing of optical thin films. Formed in 1996, Rugate Technologies has expertise in the fabrication of narrow notch infrared filters, dual-band infrared coatings, and spectral control filters for high-efficiency thermophotovoltaic devices.

As part of the acquisition, Rugate Technologies co-founder Thomas D. Rahmlow, Jr. has joined Omega Optical in the role of Senior Scientist, bringing 30 years of experience in thin-film coating design and fabrication to Omega’s engineering team. Omega also added an E-Beam/Ion-Assist coating chamber specifically configured to MWIR and LWIR coatings.
