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.
Claims32
A laser protection eyewear lens comprising:
- a) a lens substrate comprising an embedded wavelength filter having a first filter function comprising one of an edge filter function and a notch filter function having at least one center wavelength and bandwidth;
- and
- b) a multi-layer dielectric filter applied to at least one of an inside and an outside surface of the lens substrate, the multilayer dielectric filter comprising a second filter function comprising the other of the edge filter function and the notch filter function having at least one center wavelength and bandwidth,
- wherein 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 comprises a linear combination of the first filter function and the second filter function that attenuates light in at least two of a red region, a green region, and a blue region of the spectrum.
