    Do any manufacturers use sapphire glass elements?

    Just kinda curious.

    I don't know if it has a weird color cast or something, though. Maybe because of its hardness it can't be ground precisely enough for camera optics? It might not be an issue reading a watch face through a single piece of glass, but maybe it totally doesn't work refracting through multiple elements. Does anyone know?

    (BTW, what else is sapphire glass used for? Cockpit gauges, maybe?)
