摘要：

We demonstrate a microLED light source for optical sectioning structured illumination microscopy (OS-SIM). A bottom-emitting design is employed to improve the uniformity and intensity of emission by removing the anode contact from the optical path. This design facilitates the addition of a potential equalizing and light-reflecting layer to the top surface of the light source. The irradiance, uniformity of light emission, and contrast ratio of the light source are characterized. A system demonstration is performed with the light source integrated into a fluorescence microscope and used for OS-SIM imaging.
