At application of "pillow optics" for various lenses a problem of non-uniform distribution of output light can be faced. Even if input light from the source (i.e. before the lens) is a uniform parallel beam, the output light will not be uniform: Intensity is higher for central angles than for outlying angles. It takes place due to geometry of spherical pillows. To improve angular uniformity of output light, the other kind of pillow geometry can be applied instead of spherical geometry.
