Brattleboro, Vermont (July 13, 2016) - 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.

New capabilities already developed through this collaboration include athermal NIR narrow bandpass filters for LIDAR and freespace optical communications, and ultra-narrowband (sub-nanometer) bandpass filters for UV through MIR wavelengths. Omega Optical has presented papers on these new developments at recent SPIE and OSA conferences.

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.

“By bringing Omega’s custom and production capabilities to the IR, we’re able to offer high volume quantities and pricing to the market,” said Rahmlow. “We are currently producing 3rd Gen far-infrared coatings and sputter-coated mid-IR bandpass filters in volume.”

This combined knowledge and experience will enhance the focus on new technologies and expand Omega’s technical capabilities, according to President and Technical Director Robert L. Johnson, Jr. “Adding research and resources from Rugate Technologies to our high-volume production capabilities fulfills our long-term goal of offering more filters in the mid- and far-infrared.”


Brattleboro, Vermont - Omega Optical, Inc. is pleased to announce that its quality management system for manufacturing thin-film optical filters has been awarded ISO 9001:2008 certification by ISO registrar NQA.

“We are proud to be one of the few SBA-registered small businesses manufacturing thin-film filters to achieve ISO 9001:2008 certification,” said Dr. Robert Johnson, Omega Optical’s President and Technical Director. “Paired with the broadest capabilities and finest contemporary coating systems in our field, our quality management system demonstrates our ability to provide customers with a consistently superior product."

Omega Optical is committed to continual improvement of its quality management system, and using that system to meet customer requirements and regulatory obligations, according to Omega’s COO, Kieran Gallagher.

“From biomedical to aerospace, the markets we serve require optical filter manufacturing that consistently meets increasingly exacting requirements,” said Gallagher. “While Omega has used a quality management system modeled on the ISO 9001 standards for many years, our recent certification assures customers that our processes have been rigorously audited by an ISO registrar known for its expertise across diverse technical industries.”


Brattleboro, Vermont - Omega Optical's newly-launched RapidBand stock program provides fast delivery for hundreds of bandpass filter combinations in a standard 25mm diameter ring that is only 3.5mm thick.

RapidBand filters are constructed by combining longpass and shortpass edges produced at 10nm increments from 400nm to 700nm. These are assembled in a proprietary air-spaced ring designed to meet the size and quality requirements for many optical systems, and are ideal for applications from fluorescence microscopy to rapid prototyping. Longpass and shortpass edge filters can also be ordered as RapidEdge filters, and are mounted in the same 25mm ring.

RapidBand filters are manufactured with durable plasma-assisted reactive magnetron sputtered coatings, and will have 90% typical transmission, OD5 average (OD4 minimum) blocking from UV-1100nm for silicon detectors, a minimum 20.9 mm clear aperture, and ¼ λ TWD @ 633nm. Theoretical spectral curves of the finished bandpass filters are available, calculated from measured edge filter spectra.

Choose from over 400 possible RapidBand combinations and more than 55 longpass and shortpass RapidEdge filters.
