High Resolution down to <1 µm

Due to the larger numerical aperture of the paraboloidal mirror design, the diffraction-limited resolution can be 2X higher than the limit for KB mirrors. Sigray's current state-of-the-art paraboloidal mirror achieves down to <1 um resolution at the synchrotron, due to a highly sophisticated manufacturing process with <100 nm deviation from design figure.  

Above, left: The relationship between numerical aperture and theoretical resolution limit. Due to its larger numerical aperture, a paraboloidal mirror has 2X higher theoretical resolution over a KB mirror. Currently Sigray's paraboloidal x-ray mirror lens can achieve <1 µm spots.
