ABSTRACT:
A line projector is described which uses a line projector lens for receiving light from a light source which outputs a beam having a non-circular configuration. The lens receives this non-circular beam as an input and redistributes the non-circular input in two directions as rays which form a line of uniform width and intensity along its length and also forms the line with well defined ends.
