Micro Lens Array
Micro lens arrays have superior form accuracy within the submicron range and dimension in the sub-millimetre range. The micro lens array is used effectively in the imaging, illumination, and collimation of laser light. Micro lens arrays with spherical or aspherical curvature have high filling factors and minimum dead zones, making them useful for unique beam shaping applications. Cylindrical arrays produce an aberration-free image and give the best possible light efficiency and are used for the transformation of high power diode laser beams.
