Abstract
Devices having light transmittant protective layers and methods associated with such layers are provided. In one aspect, for example, a device having a light transmittant protective layer can include a substrate having a transmittance of greater than or equal to about 85 for light having at least one wavelength from about 250 nm to about 800 nm, and a light transmittant protective layer coated on the substrate. The protective layer includes at least 50 wt % AlN and having a transmittance of greater than or equal to 80% for light having at least one wavelength from about 250 nm to about 800 nm.

A device having a light transmittant protective layer, comprising:
- a substrate having a transmittance of greater than or equal to about 90% for light having at least one wavelength from about 250 nm to about 800 nm;
- and
- a light transmittant protective layer coated on the substrate, the protective layer including at least 50 wt % AlN and having a transmittance of greater than or equal to 80% for light having at least one wavelength from about 250 nm to about 800 nm.
A method of protecting a light transmitting substrate of a device, comprising:
- depositing a light transmittant protective layer on a light transmitting substrate, the protective layer including at least 50 wt % AlN and having a transmittance of greater than or equal to 80% for light having at least one wavelength from about 250 nm to about 800 nm, wherein the substrate has a transmittance of greater than or equal to 85% for light having at least one wavelength from about 250 nm to about 800 nm.
