Microarrays are imaged by an illumination and detection system that supplies excitation light through one or more optical fibers, each fiber transmitting excitation light from an excitation light source to a single spot in the microarray. Emission light from each spot is then collected by a collimating lens and converted to a signal that is compiled by conventional software into an image of the entire microarray. The optical fiber(s) and the collimating lens are arranged such that the direction of travel of the excitation light and the direction along which the emission light is collected are not coaxial, and preferably both are at an acute angle to the axis normal to the plane of the microarray.
