15″ x 15″, 0.090″ FL, Lenticular Array

Product Details Arrays of Conventional Cylinder Lenses Used as High-Efficiency Diffusers Cylindrical Axis of Lenslet is Aligned Along the First Dimension Lenticular Arrays consist of an array of conventional cylindrical lenses which efficiently divide, focus, and diffuse light rays. The focal length of each cylindrical lenslet is typically 3 to 5 times its width and its axis is aligned along the first dimension specified under array dimensions. Lenticular Arrays are ideal for use as high-efficiency diffusers within short working distances, projection screens and stereoscopic (3D) photography.
