Build Your Ideal Adaptive Optics System for Microscopy

AOKit Bio allows you to build the adaptive optics system that best suits your individual needs. Whichever microscopy method you are using, adaptive optics allows you to pre-compensate aberrations present in your imaging system and to improve your image quality.

AOKit Bio is a set of adaptive optics components, composed of a Shack-Hartmann wavefront sensor (HASO4 First for visible or HASO4 SWIR for the infrared spectral range), Mirao 52e or any other deformable mirror or phase modulator (please contact Imagine Optic in advance to check the compatibility and availability), as well as adaptive optics software. You can choose between the WaveKit Bio set of functions (SDK) or a fully functional adaptive optics software with a user interface. Both software control all functionalities of the wavefront sensor and deformable mirror, can operate these devices in closed and open-loop modes and contain image-based (sensorless) aberration detection algorithms (3N and phase diversity) adapted for microscopy applications.

We recommend implementing AOKit Bio for the following microscopy techniques: wide field, confocal, multiphoton, light sheet, STED and SIM microscopy, as well as FCS or optical tweezers.
