An instrument is disclosed with a lens system comprising an objective lens system. The objective lens system is disposed between a light source and the plurality of reaction regions. The objective lens system comprises a field lens array, and a pupil plane, wherein the pupil plane and the light source are located on opposite sides of the field lens array. The field lens array is disposed between said light source and said plurality of reaction regions, said field lens array comprising a plurality of field lens array elements, wherein the radius of the curvature, the thickness and the position of the center of the curvature of any one field lens array element in the field lens array is variable and is disposed in a light beam path between said light source and said reaction regions such that any one of said field lens array elements is capable of imaging a pupil stop located between said light source and said field lens array to a pupil located on said pupil plane, wherein an array of pupils located on the pupil plane is generated by the field lens array. |
