Lensless imaging enables widefield-of-view with a small device. This feature is useful to long-term monitaring of living cells or point-of-care devices. Previously, we developed a high performance filter for weak fluorescence imaging with a lensless device. Due to its high excitation rejection, auto-fluorescece of observation target define the detection limit. In this study, we fabricatd a bandpass filter for lensless fluorescence imaging. The imaging result shows green fluorescenct prpotein in a brain slicee clearly.
