µDM deformable mirror
µDM deformable mirror for microscopy and ophthalmology is a single-piece designed Deformable Mirror containing 91 electromagnetic actuators, disposed in an optimized pattern, and a communication card used as a controller.
Versatile, it can be implemented alone in an open-loop or along with a wavefront sensor (included in AOkit Bio) for closed-loop applications.
Features of µDM deformable mirror for microscopy
+ Fast closed-loop convergence and accurate sensorless correction with perfect linearity and absence of hysteresis
+ Preserved photon budget with achromatic, highly reflective and continuous membrane
+ Long-term stability with temporal drift automatic compensation
+ Large dynamic range with 50% of actuators stroke still available while generating 40 microns PtV of focus
+ Fine timing control with trigger-in and trigger-out features
+ Easy integration with electronics embedded in a single-piece design and connection via a USB3 cable
+ Correction up to 10th Zernike order thanks to optimized actuator layout
Available Software for muDM microscopy deformable mirror
WAVETUNE
WaveTune is a unique software that seamlessly combines wavefront measurement and correction features with extensive instrument diagnostics. This software contains all the necessary tools to calibrate the Deformable Mirror (DM). It can also operate the DM in closed-loop with HASO wavefront sensor, as well as in open-loop and perform beam shaping.
WAVEKIT BIO
WaveKit Bio is a Software Developpement Kit (SDK), available in C++ and Python, specifically designed for microscopy applications. In particular, it contains all the necessary functions to implement sensorless AO, using image-based iterative algorithms (e.g. 3N).

Applications
With Adaptive Optics (AO) for microscopy :
+ Image deeper in your sample with correction capabilities that restore diffraction-limited Point Spread Function (PSF) in non-linear (like multiphoton) or light-sheet microscopy
+ Navigate in 3D in Single Molecule Localization Microscopy (SMLM) by shaping the PSF to your needs, using astigmatism or tetrapod
With AO for retinal imaging :
+ Explore retinal cells at high-resolution by correcting ocular aberrations in Optical Coherence Tomography (OCT), Scanning Laser Ophthalmoscopes (SLO) or flood illumination modalities
