I read a great posting here by Adrian Popa about electrooptics and I'm excited about the potential for LiNb03 in modifying the refractive index of a lens to adjust slightly the focus of a LiNb03 lens. However, I don't even know the rough order of magnitude for how much change is possible (2%? 10%). Also, since some crystals are both good lens materials and good piezoelectric mediums, would you further increase a positive change in such an electrooptical material by causing its expansion when confined around the edges (this would place potentially substantial pressure on the lens further increasing the index of refraction) Also, could this be a practical application of electrooptical materials (i.e. modifying the focal distance say 5% to adjust the focus of a lens without moving anything? Thanks, John
