In this paper, we report a method of fabricating an implantable image sensor equipped a bandpass hybrid filter for highly sensitive fluorescence observation. A hybrid filter that combines an interference filter and an absorption filter enables a high excitation light removal performance in an implantable image sensor that does not use a lens. In this study, a thin hybrid filter was successfully mounted on the image sensor using the transfer method by using a laser lift‐off technique. The transferred filter has no crack. It was demonstrated that the prototype device exhibited high excitation light removal performance and was able to acquire a fluorescent image with high contrast.

带有混合发射滤光片的图像传感器,用于体内荧光成像

在本文中,我们报告了一种制造可植入图像传感器的方法,该传感器配备了用于高灵敏度荧光观察的带通混合滤光片。结合了干涉滤光片和吸收滤光片的混合滤光片可在不使用透镜的可植入图像传感器中实现高激发光去除性能。在这项研究中,使用转移技术通过激光剥离技术成功地将薄型混合滤光片安装在图像传感器上。转移的过滤器无裂纹。证明了原型装置表现出高的激发光去除性能并且能够获得具有高对比度的荧光图像。
