Abstract:
A laser protection eyewear lens includes a lens substrate comprising an embedded wavelength filter having a first filter function, and a multi-layer dielectric filter applied to at least one of an inside and an outside surface of the lens substrate that comprises a second filter function having at least one center wavelength and bandwidth. The first filter function of the embedded wavelength filter and the second filter function of the multilayer dielectric filter produce a combined filter function that attenuates light reflecting off the multi-layer dielectric filter.
