Lensless micro-imaging devices are expected to be applied to diganoses in the areas with limited medical infrastructures and IoT region, because of their inherent small size and wide field of view in comparison with conventional lens-based microscopy. However, there was a problem of emission filter performance to detect weak fluorescence. In this work, we propse a high performance emission filter for lensless imaging devices and demonstrate cell imaging by an ultra-small lensless fluorescence imaging device.
