SPUTTERING PROCESS

Photonics Spectra

Omega Optical Inc.Request Info
 
Omega Optical.jpgOmega Optical Inc. has added dual-magnetron reactive sputtering to its surface coating capabilities. Available for many applications, particularly those where every photon is critical, the technology employs a proprietary plasma/ion process that is controlled by a multidimensional computer-aided design and real-time monitoring system. It provides precise layers that are extremely dense and shift-free and offers sputtering rates more rapid than those achieved by typical sputtering processes. It produces coatings that match theoretical designs, and there is a high degree of uniformity from batch to batch and from piece to piece. The process results in high filter performance in support of high-velocity manufacturing environments.

GLOSSARY
photon
A quantum of electromagnetic energy of a single mode; i.e., a single wavelength, direction and polarization. As a unit of energy, each photon equals hn, h being Planck's constant and n, the frequency of the propagating electromagnetic wave. The momentum of the photon in the direction of propagation is hn/c, c being the speed of light.
