Product Description



H9/HV1800-2200 Convex Watch Glass With Anti - Reflective Coatings



Product Description:


Sapphire plano convex lens 
Sapphire material has excellent optical and mechanical properties, such as high strength, hardness, wear resistance, unique high temperature resistance, acid and alkali corrosion resistance and high dielectric properties, etc., in a wide spectrum (250-5500nm) with high transmittance. Therefore, sapphire lens can be used as optical surface, corrosion resistant surface or precision imaging optical instrument and focusing optical instrument accessories, common can be used for high-grade clocks and watches, jewelry, and all kinds of glasses, transparent lamps and lanterns and goggles.

Arched Sapphire Crystal Watch Glass Detail :


Arched Shape , Clear Colour , Can be with AR-Blue Coating , can be Coating in different colours too .are nearly unbreakable crystals making them highly prized by watchmakers.

It has high compressive strength and a high melting point. It is also resistant to UV radiation darkening. Our sapphire optical windows are not coated, but a single layer coating of MgF2 on each surface of the window increases the single surface transmittance to 99% throughout the entire visible spectral region.
These watch crystals can be glued into most watch cases or pressure fit into most plastic watch crystal gaskets. Each sapphire watch crystal comes with a slightly polished bevel edge to give the watch crystal a nice finished look once it has been installed.
