Microlens Array

Microlens array contains multiple lenses formed in a one-dimensional or two-dimensional array on a supporting substrate. A typical microlens may be a single element with one plane surface and one spherical convex surface to refract the light.

Square microlenses is commonly used for beam homogenization and shaping, yielding spot patterns or a square flat-top pattern. The lenses feature a high fill factor which eliminates zero-order hot spots in the illuminated field. Square lenses are often used in pairs, in conjunction with a PCX lens. Microlenses are well suited for applications that require high efficiency and non-gaussian uniformity includes welding, drilling, laser ablation, and fiber coupling.
