Miniaturization of imaging systems has become an important requirement for studying the brains of freely behaving animals (mice, birds, etc.). The author presents a 1-photon miniscope device with significant mechanical (weight: 1.3g, small size: 10mm $\times17$ mm $\times12$ mm) and optical (lateral resolution: 1 $\mu \text{m}$ , magnification: 12.5, etc.) advantages compared to existing systems. This device can be used to image and study fine brain structures and its design is well-suited for the incorporation of future generations of depth scanning, aberration correction, structured illumination and wireless approaches.
