Wavefront sensors have various perceived benefits but here are 10 objective reasons that have made Shack-Hartmann a trusted standard in the field.

  1.  Real time measurement (up to several kHz)
  2. Achromatic
  3. Absolute measurement (typ. lambda/100, lambda/1000 achievable)
  4. Linearity > 99.9%
  5. Huge dynamic range > 1000 lambdas
  6. Wavefront and intensity maps measured independantly
  7. Simple and robust technology
  8. Insensitive to vibrations
  9. Wavefront measurement even with less than 100 picojoules
  10. 100% beam acquired, user mask not mandatory


Shack-Hartmann wavefront sensors are widely used in various fields of optics, such as astronomy, ophthalmology, and microscopy, due to their numerous benefits. These sensors can measure wavefront distortions caused by atmospheric turbulence, optical aberrations, or other factors with high accuracy and sensitivity, making them a valuable tool for adaptive optics systems. Those sensors are also non-invasive and provide real-time measurements, making them ideal for measuring wavefronts in living tissue. Additionally, these sensors can be easily integrated into optical systems, and their compact size and low power consumption make them suitable for field use. Overall, S-H wavefront sensors are a versatile and powerful tool for precise wavefront analysis and have a wide range of applications in the field of optics.
