Abstract
An optical system is disclosed that can be used for fluorescence filtering for molecular imaging. In one preferred embodiment, a source subsystem is disclosed comprising a light source and a first set of filters designed to pass wavelengths of light in an absorption band of a fluorescent material. A detector subsystem is also disclosed comprising a light detector, imaging optics, a second set of filters designed to pass wavelengths of light in an emission band of the fluorescent material, and an aperture located at a front focal plane of the imaging optics. A telecentric space is created between the light detector and the imaging optics, such that axial rays from a plurality of field points emerge from the imaging optics parallel to each other and perpendicular to the second set of filters.
