Cylindrical lenses, also called FAC fast-axis collimating lenses, generally use quartz rods with a diameter of 63um or 105/125um fibers with side coatings to collimate laser fast-axis divergence and improve optical power coupling efficiency. Coating FAC fast-axis collimating lenses is difficult. Multiple glass rods or fibers of a specified length generally need to be fixed in parallel in a fixture, loaded into the coating machine, and coated on the front and back in two operations. After coating, each glass rod or fiber is cut into small sections for use in individual products.
