Abstract
An optical device () is disclosed, comprising a collimator () and a first lenslet array () and a second lenslet array (). The first lenslet array and the second lenslet array are provided with the same tessellation pattern, aligned with each other and arranged such that a projection () of a light source () is focused on the second lenslet array, which is configured to emit non-focused light. At least some of the lenslets of the second array are formed such that a ratio of their sagittal and meridional dimensions varies at least along the meridional direction (M) of the second lenslet array, based on the varying shape of the projection of the light source as seen by said lenslets, so as to achieve an improved mixing, intensity and uniformity of light emitted from the optical device.
