Diffractive Optics

We leverage diffractive optics to create novel structured illuminations that enhance the capabilities of microscopic systems. Our successful developments include needle beams (NBs) for biomedical microscopes and linear-array-spot-excitation (LASE) for imaging flow cytometry. Our future research will focus on exciting scientific explorations, such as super-resolution NBs and 3D arbitrary-shaped laser foci.
