To address the major challenges to obtain high spatial resolution in snapshot hyperspectral imaging, 3D printed glass lightguide array is developed to sample the intermediate image in high spatial resolution and redistribute the pixels in the output end to achieve high spectral resolution. Curved 3D printed lightguide array can significantly simplify the snapshot hyperspectral imaging system, achieve better imaging performance, and reduce the system complexity and cost. Two‐photon polymerization process to print glass lightguide array is developed, and the system performance with biological samples is demonstrated. This new snapshot technology will catalyze new hyperspectral imaging system development and open doors for new applications from UV to infrared. [ABSTRACT FROM AUTHOR]
