| 摘要 |
An optical detection system (100) includes an optical element (116, 202, 502) that directs emission radiation (108), which traverses away from an optical collection path (122), to the path, wherein the emission radiation is emitted by a radiation sensitive material in a sample (204) under study in response to the material absorbing excitation radiation, and the emission radiation has a spectral characteristic that corresponds to the material.
