Simple wavefront measurement

Based on HASO4 First wavefront sensor, the Wavefront Imager is designed to calibrate MicAO adaptive optics device or measure aberrations in your optical microscope with an accuracy of lambda/100. The Wavefront Imager simplifies the calibration process of MicAO and improves the quality of closed-loop optimization. This plug-and-play device offers an easy integration thanks to its C-mount opto-mechanical coupling and it fits into the camera port of MicAO or any optical microscope. WaveView software, which is delivered with Wavefront Imager, offers the analysis of the wavefront and Zernike polynomial decomposition.
