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.

System and method for providing radiation having annular profile

A system includes a first element configured to receive a plurality of color components that are spatially separated, wherein each of the plurality of color components comprises light of a respective wavelength, and to focus the plurality of spatially separated color components onto a first surface of a second element. The system also includes a second element having a first surface and a second surface, wherein the second element is configured to receive the plurality of color components via the first surface, to transmit to the second surface uniform light comprising the plurality of color components in a blended state, and to emit the uniform light via the second surface. The system also includes a slit lamp configured to receive the uniform light.

Illumination source and method for use with imaging device

A diode pumped laser system includes a laser cavity with an active laser medium. A laser diode, with an emitter region having an output facet that produces light at a frequency .lambda..sub.1, is the pump source for the laser medium. A coupling optics is positioned on an emission path of radiation from the emitter region and is optically coupled and spaced from the diode. The coupling optics produces stray radiation. An optical fiber, with a first end and a second end, is included. The first end of the fiber is oriented with respect to the coupling optics such that radiation from the emitter region is optically coupled into the optical fiber. The second end of the fiber is coupled to the laser cavity. A detector is positioned in a spaced, adjacent relationship to the coupling optics along an emission path of the stray radiation. The detector detects at least a portion of the stray radiation and produces a detected output in response to the stray radiation. A signal processor is coupled to the detector, and receives the detected output to produce a processed output that is representative of a detected characteristic of the laser system.
