ABSTRACT:
A system of optics used to provide illumination through an objective at a precise inclination angle and with uniform intensity across an illuminated field. The system provides annular illumination with a continuously variable diameter at the back aperture of an objective. The resultant illumination field at the imaging plane of the objective includes rays with a single inclination angle with respect to the optical axis of the objective. This incidence angle is determined by the position of an axicon lens. The imaging plane is illuminated from 360 degrees rotation about optical axis of the objective.
