![]() ![]() Kits include a single sensor head and two MLAs. The Item #s for these wavefront sensors have a prefix that refers to the sensor head type (WFS31, WFS40*, or WFS20), and a suffix that refers to either the MLA type (-5C, -7A, or -14AR) or the kit type ( -K1 or -K2). As summarized in the table above, we currently offer high-speed wavefront sensors along with three MLA options with different lenslet pitches and focal lengths for optimal accuracy and wavefront dynamic range for your application. These wavefront sensors include both a CMOS-based sensor head and a microlens array (MLA). Thorlabs' Fast Shack-Hartmann Wavefront Sensors provide accurate measurements of the wavefront shape and intensity distribution of incident beams. The intensity and location of each spot is analyzed to dynamically measure the wavefronts of laser sources or characterize the wavefront distortion caused by optical components. For more details on the theory of Shack-Hartmann wavefront sensing, see the SH Tutorial tab. When a wavefront enters the lenslet array, a spot field is created on the camera. Schematic of a Microlens Array Focusing a Distorted WavefrontĪ Shack-Hartmann sensor consists of a lenslet array and a camera.
