Dear Customers,
Our standard sapphire crystals come in four shapes: flat, single dome, double dome, and dish-like dome, as shown in the images for your reference. Additionally, to reduce glare from strong light, some sapphire crystals are coated with one or more layers of anti-reflective coating, typically applied on one or both sides (inner and outer surfaces). This helps improve readability, especially in sunlight.There are also additional specifications available, such as light transmittance, upon request.
