Abstract
A coaxial illuminator adapted for surgical coaxial illumination and viewing including an opaque housing defining a longitudinal axis and having a tilted, anti-reflection coated window located at one end of the housing. A beamsplitter is located within the housing and is positioned so as to reflect light, from a light source, along the longitudinal axis of the housing through the window to illuminate the object and to permit image light from the object being viewed to pass along the longitudinal housing through the beamsplitter. An absorber is positioned to absorb light which passes from the light source through the beamsplitter unreflected.
