Thorlabs Shack-Hartmann Wavefront Sensor
The Thorlabs Shack-Hartmann Wavefront sensor is an indispensable tool for
detection and optimization of wavefront distortions that would otherwise impact the
beam's focusability and the image definition within an imaging system. It is an
economically priced instrument designed for general lab use and production floor
testing.
The WFS series of Shack-Hartmann wavefront sensors provide accurate, high-
speed measurements of the wavefront shape and intensity distribution of beams.
This is done by analyzing the location and intensity of spots (spotfield) formed by
imaging a beam of light onto a CCD/CMOS array with a microlens array as shown in
the figure below. With Thorlabs' Shack-Hartmann wavefront sensor it is possible to
optimize dynamically the wavefronts of laser sources, characterize the wavefront
distortion caused by optical components, and provide real-time feedback for the
control of adaptive optics.
The sensor operation confirms to International Standard ISO 15367:
"Laser and laser-related equipment - Test methods
for determination of the shape of a laser beam wavefront"
