Abstract
A diffuse illuminator device is disclosed for providing uniform illumination onto a target. A generally tubular outer baffle, which has a proximal and an open distal end, defines an optic axis. A generally tubular inner baffle which is open at its proximal and distal ends is coaxially disposed within the outer baffle. An annular illuminator, positioned at the proximal end of the outer and inner baffles, directs a ring of illumination into an annular light tunnel which is defined by the space between the inner and outer baffles. This arrangement allows viewing of the target through the inner baffle. The inner baffle may also be adjusted along the optic axis in order to vary the illumination structure of the light on the target.
