Abstract
Wide-field fluorescence imaging systems and methods. A bi-telecentric optical imaging system comprising imaging optics arranged and positioned such that a first telecentric space is created or exists between a sample platform and an entry aperture stop wherein Principal or chief rays from a plurality of field points on the sample platform are parallel to each other when passing through a first filter; and such that a second telecentric space is created or exists between a light detector and an exit aperture stop wherein the Principal or chief rays from the plurality of field points are parallel to each other when passing through a second filter. In this manner, light collected from different points in the field of view pass through the first filter at the same angles and also through the second filter at the same angles to thereby reduce or eliminate angular spectral shifting effects.
