The Thorlabs WFS10-5C is a high-resolution wavefront sensor employing the Shack-Hartmann principle for precise optical wavefront measurement and analysis. A microlens array divides the incident beam into smaller beams, each focused onto a CMOS camera sensor. Deviations in focal spot positions from reference locations reveal wavefront distortions, making this instrument essential for adaptive optics, laser characterization, and optical system alignment.
