Perfect Lens Finishing in the Workshop with the Diafine by Essilor
The Diafine is a mechanical lens finishing device designed for direct use in opticians’ workshops. This tool allows for precise polishing and beveling of ophthalmic lens edges with exceptional consistency. Thanks to its compact design, it fits easily onto any stable and level workbench, without the need for a direct water connection. Its humidification system relies on an internal water tank and a sponge that maintains constant contact with the grinding wheel, ensuring optimal polishing performance.
The machine features a grinding wheel specifically engineered for polycarbonate lenses, a material widely used in modern eyewear. To achieve a smooth and satisfactory result, lenses must be pressed firmly against the wheel during use. Special attention should be paid to the cleanliness of the sponge, as it tends to become dirty quickly, directly affecting the quality of the finish. The Diafine is powered via a standard electrical outlet and operated using a switch located at the rear. It is compatible with both European and American voltage standards.
The Diafine offers multiple finishing options: mini-beveling, V-shaped edging, and precision retouching adapted to the lens shape. Each band or groove on the grinding wheel is dedicated to a specific type of edge finish. The device operates quietly, with an average sound level of 75.2 dBA, allowing for comfortable use even in quiet environments.
Regarding maintenance, the device offers easy access to components such as the water tank, base, and front cover, simplifying cleaning tasks. The grinding wheel can be replaced by following the supplied instructions and safety guidelines. The Diafine should not be used on glass (mineral) lenses, in order to preserve its performance. All electrical repairs must be carried out by certified professionals, in accordance with safety regulations.
The Diafine is therefore an ideal precision tool for demanding professionals looking for a simple, reliable, and high-performance solution for manual optical finishing tasks.
