The focusing lens usually has two convex curvature equal, the most suitable material and the like in the case of ratios from both sides of the lens, the image distance and object (conjugated ratio) at between 0.2 to 5. Lenticular widely used aggregation from a point light source or the image is transmitted to other optical systems, more suitable for use in a 1: 1 imaging and multi-component systems. Since the object and image distances are equal or approximately equal, the distortion can be minimized. So when the distance ratio (object distance: image distance) conjugate in 5: 1-1: between 5 and when you want to get a minimum of distortion, the lenticular lens is the best choice. Hironobu lenticular lens offers a variety of materials, including H-K9L, UV fused quartz.
