Microlens arrays (or micro-lens arrays) are one- or two-dimensional arrays of microlenses, i.e., rather small lenses (lenslets). In most cases, the lenslets form a periodic pattern either of square or hexagonal type, where the lens pitch is a few hundred micrometers, some tens of micrometers or even less.

Two-dimensional microlens arrays are available with spheric, aspheric, or astigmatic lenses, on rectangular, hexagonal or customer-specified grids. The microlens array can be fabricated within a larger planar substrate to enable ease of mounting, without the mount impinging on the clear aperture of the microlens array.

An aspherical lens made by a compression molding method can replace the three spherical lenses used in the optical lens of the optical disc reader. Due to the high precision of the molded aspherical lens, it is possible to control and correct the axial aberration of the large numerical aperture, and also reduce the weight and cost of the original optical lens by 30 to 50%.

This thesis propose a method for minimizing the focused spot size of an elliptically-diverging laser diode beam by means of a circular aperture and single plano-convex aspherical microlens. The proposed microlens is fabricated using an excimer laser dragging method and has two different profiles in the x- and y-axis directions.
