1. A probe for performing endomicroscopy, comprising:
a light source;
a waveguide coupled to the light source;
a diffraction grating,
the waveguide directing light from the light source to the diffraction grating; and
a lens having a first aspheric surface and a second biconic surface,
the second biconic surface having a first axis associated with a first radius of curvature and a second axis associated with a second radius of curvature,
the second axis being perpendicular to the first axis,
the first radius of curvature and the second radius of curvature having the same sign, and
diffracted light from the diffraction grating being directed into the aspheric surface of the lens and being emitted from the biconic surface of the lens towards a transparent cylindrical surface of the probe.
