Precision optics company Omega Optical Holdings has acquired Evaporated Metal Films Corp. (EMF) and Optometrics Corp. Omega has completed the acquisition from Dynasil Corp. of America. The businesses provide Omega with capabilities that complement its focus on serving challenging optical applications in high-growth markets, said Michael Cumbo, CEO of Omega. “The impressive scale of EMF’s thin-film deposition chambers dramatically increases our ability to offer precision coatings for large optics with diameters up to 2.7 m,” Cumbo said. “Optometrics brings a unique combination of ruled, holographic, replicated, and filtered diffraction gratings that are highly valued, particularly in applications where compactness, efficiency, and precise wavelength selectivity are required.” EMF joins Omega’s thin-film filters operating division and will play a role in the platform’s nascent laser optics division. Optometrics joins Omega’s diffractive optics operating division.
