Abstract
An instrument for processing and/or measuring a biological process contains an excitation source, a sample holder, an optical sensor, an excitation optical system, and an emission optical system. The sample holder is configured to receive a plurality of biological samples. The optical sensor is configured to receive an emission from the biological samples. The excitation optical system is disposed along an excitation optical path and is configured to direct the electromagnetic radiation from the excitation source to the biological samples. The emission optical system is disposed along an emission optical path and is configured to direct electromagnetic emissions from the biological samples to the optical sensor. The instrument further contains a plurality of filter assemblies configured to be interchangeably located along at least one of the optical paths. The plurality of filter components includes a first filter assembly characterized by a first optical power and a first filter having a first filter function, the first filter function characterized by at least one of a first low-pass wavelength or a first high-pass wavelength. The second filter assembly is characterized by a seco…
