Abstract
An apparatus having a waveguide and a freeform collimating lens. The waveguide is characterized by a waveguide axis and a planar end having a normal axis that is inclined at an end angle that is greater than 0 degrees with respect to the waveguide axis. The freeform collimating lens collimates light leaving the planar end of the waveguide into a collimated light beam characterized by a beam direction that is parallel to the waveguide axis. The apparatus inhibits reflections from the planar end of the waveguide from propagating back down the waveguide while providing a collimated light beam having a direction parallel to the axis of the waveguide.
