Wedge-shaped lensless laser focusing device

A method of creating an output pattern from an unfocused laser beam being projected along a projection axis, the method comprising the steps of:

• positioning a first wedge plate at a reflection angle relative to the projection axis, the first wedge plate including a face surface extending from an inlet end to a discharge end;
• positioning a second wedge plate at the reflection angle relative to the projection axis, the second wedge plate extending in an opposite direction relative to the first wedge plate, the second wedge plate including a face surface extending from an inlet end to a discharge end;
• positioning the first wedge plate relative to the second wedge plate to define an inlet opening between the inlet ends of the first and second wedge plates and a discharge opening between the discharge ends of the first and second wedge plates;
• and
• positioning the first and second wedge plates along the projection axis such that the input laser beam is received within the inlet opening, wherein the input laser beam is reflected off of the face surfaces and out of the discharge opening to define the output pattern.
