Claim:
1. A solar simulator system comprising: a first light source configured to generate a first optical beam; a first tipping lens disposed in front of said first light source at a location along a path of said first optical beam; a first spectral filter assembly configured to receive the first optical beam from said first tipping lens, split the first optical beam into a first plurality of beamlets, and then filter the first plurality of beamlets; a first re-imaging assembly configured to re-image the first plurality of beamlets received from the first spectral filter assembly so that the beamlets of the first plurality mutually overlap in an illumination plane; and a re-sizing lens configured to change a cross-sectional dimension of an optical beam impinging thereon, wherein said re-sizing lens is disposed along an optical path that starts at said first re-imaging assembly and ends at the illumination plane.
