Abstract
An imaging assembly and processing system that includes a sample platform having a target region which can hold a sample, where the sample can be marked with fluorescent or phosphorescent markers. The imaging assembly can have an excitation light module proximate to the sample platform that emits light to excite the markers, and a lens module positioned to receive emission light from excited markers in target region. At least one series filter assembly or interference filter can be arranged in front of, behind, or both in front of and behind the lens module. The assembly includes a light sensor and a processor and imaging module configured to process data captured by the light sensor. Images of the sample are generated based on the emission light from the sample that transmit through and are filtered by the lens assembly and series filter assembly or interference filter.
