WIDE-AREA FLUORESCENCE DETECTION SYSTEM FOR MULTI-PHOTON MICROSCOPY

摘要

A multi-photon microscope (100) has an illumination source (102), an objective lens unit (104) arranged in an optical path of the illumination source (102), a first light collection system (106) arranged to collect a first portion of light emitted from a sample when the sample is illuminated by light from the illumination source (102), and a second light collection system (108) arranged to collect a second portion of light emitted from the sample when the sample is illuminated by light from the illumination source (102). The first portion of light when collected by the first light collection system (106) and the second portion of light when collected by the second light collection system (108), together provide a means of collecting as much light from as many angles as possible emanating from an emitting point source. This collection scheme has the potential to approach the total emission collection of light from an emitting point source depending on the optical properties of the sample being imaged.
