DSU
What it is
How it works
The DSU uses a spinning disk with a pattern of slits to create a virtual pinhole as the disk rotates. The DSU is designed to improve the balance between confocality and light throughput.[3]
The DSU uses fluorescence excitation light from a white light source such as a xenon or mercury lamp. The excitation light is filtered, reflected through the spinning slit disk, passed through the objective, and directed onto the specimen, while emitted fluorescence returns through the disk for wavelength selection and image formation.[4]
