Abstract:
A narrow angle illumination light source for an ophthalmic surgical laser system includes multiple light emitting diodes (LEDs), multiple corresponding ball lenses, multiple corresponding upper apertures located between the LEDs and the lenses (optional), and multiple corresponding lower apertures located below the lenses. The light passing through each upper aperture and corresponding lens forms a light cone having a defined divergence angle and cone axis angle; the light cone only illuminates the corneal and sclera of a docked eye without illuminating the patients nose and orbit. The lower apertures may have distinctive shapes to aid video focusing. The multiple LEDs are distributed uniformly in the circle, and may be divided into multiple independently controllable segments which allows directional illumination The LEDs also have controllable brightness to allow images of darker and brighter illuminations to be taken in short succession.
