Abstract
We report on the solgel method of fabrication of thin films of high optical quality and with tunable index of refraction. The resulting coatings are hard, durable and robust against humidity and common organic solvents. Bragg mirrors and edge filters have been made by stacking these films. A blue light-blocking edge filter made by stacked layers shows a transmittance of less than 1% in the stop band region while maintaining a high transmittance of over 80% in the rest of the visible spectral region with an integrated photopic transmittance of 89.7%.
