Abstract
An ophthalmic illumination device has an illuminating body. The illuminating body has a through-opening whose side wall is formed by a member made of an opalescent material. A light source is housed inside the illuminating body and a light guide adapted to radially convey light beams emitted by the light source towards an axis of the through-opening is positioned between the light source and the opalescent member. The ophthalmic illumination device can generate extremely homogenous shafts of light, while minimizing occurrences of dark portions.

A device comprising:
- an illuminating body having a through-opening,
- a light source housed inside the illuminating body, and
- a light-guide configured to radially convey light beams emitted by the light source towards an axis of the through-opening,
- the illuminating body being configured to emit a light shaft towards an eye of a patient through the through-opening, wherein
- the illuminating body comprises an opalescent member, the opalescent member forming a side wall of the through-opening, the light-guide is positioned between the light source and the opalescent member, thus obtaining a substantially uniform illumination of the opalescent member and a homogeneous light shaft from the illuminating body.
