Abstract

System and method for fluorescent light detection from biological samples to enhance the numerical aperture and/or reduce the cross-talk of the fluorescent light. The numerical aperture is enhanced by changing the material of construction of a numeral aperture (NA) enhancing element, such as a truncated sphere, in the fluorescent light detection system, such that NA enhancing optial element (40) is constructed of a different material than the housing (560) containing the sample. To eliminate the spherical aberration, the housing is positioned in a source plane that is offset from the theoretical aplanatic source plane. Cross-talk is reduced by using a mask (440).
