Extended Range Viewports (ERV)

MDC’s precision-engineered, extended range viewports (ERV) feature our VacOptix® sealing technology. This premier proprietary technique enables hermetic sealing of exotic optical materials previously unavailable in the industry. With an overall transmission range of 100 nm to 20 microns, these high-quality laser optics viewports provide the widest energy transmission range across the entire optical spectrum, from deep ultraviolet to far infrared wavelengths.
