A snapshot Image Mapping Spectrometer (IMS) with high sampling density is developed for hyperspectral microscopy, measuring a datacube of dimensions 285 × 285 × 60 (x, y, λ). The spatial resolution is -0.45 μm with a FOV of 100 × 100 μm2. The measured spectrum is from 450 nm to 650 nm and is sampled by 60 spectral channels with average sampling interval ∼3.3 nm. The channel's spectral resolution is ∼8nm. The spectral imaging results demonstrate the potential of the IMS for real-time cellular fluorescence imaging.
