“…While these sensors were used for adaptive optics in astronomy and high-energy lasers, they have been applied to a wide range of problems recently, including laser beam characterization [5,6], fluid turbulence measurement [7][8][9], optical system alignment [10], ophthalmic metrology [11], wafer metrology [12], optical metrology for both large [13] and small [14] optics. The basic measurement principle is similar to the Hartmann test of the early 1900s.…”

Development of a calibration standard for spherical aberration

et al. 2013

There are no calibration standards currently available for metrology equipment used to measure spherical aberration. We have selected a set of plano-convex lenses that can be used as spherical aberration calibration standards. The key parameters of the lenses were measured using a nodal optical bench and a low coherence interferometer. Spherical aberrations of the lenses were measured using a commercially available aberrometer the CrystalWave™, based on a Shack-Hartmann wavefront sensor. The lenses were then modeled in optical modeling software, where the spherical curvatures of the lenses were adjusted to match the key parameters. The measured spherical aberrations were then compared to the values provided by the modeling software.

“…Consequently, the optic behaves as if it is a lens; this effect is called thermal lensing. In this part of our study, we measured the thermal lensing in the FR using a Shack-Hartmann wavefront detector [4] (SHWD, Wavefront Sciences model 285336). Pr( arrangement are (I) the SHWD is higher in sensitivity at 633 nm than at 1.06 tm and (ii) power balancing to ensure constant intensity on the SHWD is not necessary as the pump beam power is varied.…”
