HASO4 R-Flex50 is an optical metrology tool that gives the possibility of using
several characterizing wavelengths for optical components and system inspection.

Key applications

  • Analyze the transmitted wavefront of optical systems with double path configuration
  • Characterize optical surfaces
  • Characterize chromatic aberrations
  • Input a divergent beam for direct wavefront measurements


HASO R-Flex unites Imagine Optic’s patented HASO Shack-Hartmann wavefront sensors with a collimator and a focusing module to provide users with a versatile and turnkey solution for precision characterization of optical systems and surfaces. Its standard accuracy of λ/100, λ/200 in double pass configurations, and insensitivity to vibrations or atmospheric turbulence enable users to perform measurements that meet the most stringent requirements for reliable, repeatable results. Even more, accuracy can be further increased if the measured aberration is close to the diffraction limit.

Because different users have different needs, the f/# of HASO R-Flex can be adapted to each user’s requirements by choosing the focusing module best suited for the task at hand. As the sample f/# defines the best focusing module, Imagine Optic offers factory models that are available from f/#=1 to f/#=15 to ensure maximum sampling points, whereas custom models for special needs can equally be delivered. Please see the product page of standard focusing units.

Recently, we developed HASO4 R-Flex50 for two wavelength ranges; 400-700nm (VIS) and 650-1100nm (NIR). This broadens the capacity of the HASO R-Flex to inspect optical components in term of chromatic aberrations for example.

Characterizing large optical components or complex systems is performed easily as the exit beam is divergent, thereby allowing users to set to focal spot to any point. When set at the centre of concave mirrors, surface defects can be measured and analyzed.

HASO R-Flex is delivered with WaveView wavefront measurement and analysis software that runs under Windows 7. It displays aberrations in real-time so that users can immediately see the effects of various positioning or alignment adjustments.

Its small footprint allows to it be easily mounted onto translation stages so samples can be measured on-axis or at any point in the field.
