Figure 2
Schematic diagram of the zone plate focusing optics. The phase zone plate and OSA are aligned by the XYZ positioning stages. These components are mounted on the same translation stage (stage x), which can be moved by 60 mm on the aligned light axis to enable sample centring using the optical microscope. The position repeatability of stage x is monitored by the linear gauge with 100 nm resolution.
