Figure 2
Optical diagram of the sample, the microscope objective lens and a modulator microlens arrangement. The microlens is positioned at the back-focal plane of the objective lens, the same location where an objective lens aperture is typically used. The formula below the micolens describes the geometrical optics relation between the sample defocus Δf, the objective lens focal length f0 and the microlens focal length fm.
