Abstract
A system includes a focusing element configured to receive electromagnetic radiation coaxially and to focus the electromagnetic radiation to generate focused radiation. The system also includes a refracting element having an associated focal plane. The refracting element is configured to receive the focused radiation, and to refract the focused radiation to produce refracted radiation having an annular pattern at the focal plane. The system also includes a slit lamp having a receiving element to receive the refracted radiation.
