ABSTRACT:
An accessory is provided to convert a conventional microscope to a microspectrofluorimeter. The accessory includes a filter disc having bandpass filters separated by opaque segments. The filter disc is rapidly and continuously rotated to move the filter sequentially into the optical path between a wideband light source and a microscope sample. Photon counting of radiation from the sample is synchronized to the position of the filters during rotation by means of synchronization marks on the filter disc. The same accessory may be positioned between the sample and a detector to detect emitted light of different frequencies.
