Lenticular Arrays
A lenticular array is a closely-packed array of conventional cylindrical lenslets. These arrays are quite suitable as one-dimensional diffusers, and some are acceptable for 3D photography (the focus must be located at the back, plano side of the array). Light striking the lenticular array is diffused only in the direction across the cylindrical lenslets; there is no diffusion along the lenslets. As the f-number of the lenslets decreases, the angle of diffusion increases depending on the relative size of the light source as compared with the lenslet spacing. A variety of diffusion angles are possible as our arrays have lenslet f-numbers ranging from f /1.2 to f /5.4. Often it is desired to diffuse light in more than one dimension. For this case we offer crossed lenticular arrays, such that the same or a different lenticular array can be molded on the back side of the sheet. Lenslet cylindrical axis is aligned along first dimensions.
