Focusing Range

The distance range through which a laser diode module can be focused to achieve an ideal spot size. Typically specified from the face of the module to past collimation. Although a laser diode module can be used at distances shorter than the minimum focusing range, it's spot size will be larger than the focused spot at this minimum distance. It is important to note that the focused spot size will increase with distance from the module. At long distances, the optimum focus condition is a collimated beam with minimum divergence.
