Abstract: The invention provides an optical collimator assembly having an optical fiber for transmitting a beam of light, a lens for substantially collimating a beam of light received from the optical fiber, and a light transmissive element disposed to receive a beam of light from the lens for correcting an angular deviation in the beam of light received from the lens. If desired, two wedges are used to correct an angular deviation of a beam exiting a collimator, wherein the two wedges have a relative rotational angle with respect to each other. The invention further provides a method for making an array of collimators having output beams substantially parallel to an axis of the collimator, or lens or lens system.
