Manufacture of lens array

Abstract

Abstract PURPOSE:To increase the degree of freedom of lens curvature control by laminating with plural a heat-deformable resin pattern plural heat-deformable resin thin films. CONSTITUTION:The heat-deformable resin thin films 102 are narrowed down in pattern width from a lower layer to an upper layer to obtain the heat- deformable resin pattern 101 which is sectioned as shown in a figure. This heat-deformable resin pattern 10 is heated to lower the viscosity of the heat- deformable resin and cause fluid deformation. Namely, the heat-deformable resin pattern 101 is formed by laminating the heat-deformable resin thin films. The radius of curvature of the obtained microlens 103 can free be varied by adjusting the pattern width of the heat-deformable resin thin films 102 and the number of stages. Consequently, the lens array which has the extremely large degree of freedom of curvature radius control can be manufactured.
