Initial Challenges

AR Coating Application

Perfecting the application of multiple antireflective (AR) layers without compromising the crystal's inherent clarity was a significant challenge. This process required innovative solutions to ensure that each layer was applied consistently and evenly.

Precision Cutting

Achieving the necessary precision in cutting and shaping the sapphire crystal to fit seamlessly within the unique Aventi case was another hurdle. The precision required was unparalleled, demanding meticulous in-house machining.

Breakthroughs

Proprietary AR Coating Techniques

Aventi developed proprietary techniques for applying the 14 layers of anti-reflective coating through a vapour deposition process. This innovation allowed for even and consistent coating without altering the sapphire crystal's clarity.

Custom Fabrication and Machining

To accommodate the Aventi Pink Champagne's unique case shape, each piece of sapphire crystal was custom-cut and polished in-house. This process ensured a perfect fit and flawless finish, with a remarkable tolerance of 0.02mm.
