Description:

This work demonstrates 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 are characterized.
