We present an imaging system that collects hyperspectral images of cells travelling through a microfluidic channel. Using a single monochrome camera and a linear variable bandpass filter (LVF), the system captures a bright field image and a set of hyperspectral fluorescence images for each cell. While the bandwidth of the LVF is 20 nm, we have demonstrated that we can determine the peak wavelength of a fluorescent object’s emission spectrum with an accuracy of below 3 nm. In addition, we have used this system to capture fluorescence spectra of individual spatially resolved cellular organelles and to spectrally resolve multiple fluorophores in individual cells.
