<p>The present invention relates to an apparatus to illuminate a sample. The apparatus comprises of a sample plane having an illumination region onto which the sample is arranged; an excitation unit having a light source to generate an excitation light; and a lens unit, having a micro lens array where the micro lens array comprises a plurality of lenses arranged in a two dimension arrangement, to receive the excitation light and generate an illumination light that is directed towards the illumination region. The lens unit produces a homogeneous illumination light that is projected on the illumination region of the sample plane with high illumination efficiency.</p> |
