As with objective lenses, a condenser lens with a maximum numerical aperture of greater than 0.95 is designed to be used under oil immersion ( or, more rarely, under water immersion ), with a layer of immersion oil placed in contact with both the slide / coverslip and the lens of the condenser.

By using oil immersion high NA objective during DLW process, 300 nm fabrication feature size on GO film has been realized, and therefore the minimum lens size has been shrink down to 4.6 �m in diameter, which is the smallest planar micro lens and can only be realized with metasurface by FIB . Thereafter, the focal length can be reduced to as small as 0.8 �m, which would potentially increase the numerical aperture ( NA ) and the focusing resolution.
