mirao 52-e Electromagnetic Deformable Mirror

mirao is a unique technology that overcomes many of the barriers that limited deformable mirror performance in the past.  mirao’s actuators use electromagnetic energy to deform the mirror’s surface up to ±50 µm(1) – the majority of commercially available mirrors only offer a fraction of mirao’s stroke.  By individually applying either positive or negative voltages to mirao’s 52 actuators, they can be instructed to either "push" or "pull" the reflective membrane to create complex Zernike forms up to the 6th order with extreme precision.  In addition to its excellent optical quality, the fact that mirao functions with almost any beam wavelength and intensity combined with its low actuator input voltage makes it ideal for ophthalmic applications (click here to see an independent study on deformable mirror performance on the SPIE website).

One of the main innovations in the new mirao 52-e is that the electronic driver unit has been totally redesigned.  The unit’s new compact size, half that of its predecessor and now one of the smallest on the market, incorporates several important enhancements and, even more, is fully plug-and-play compatible via a standard USB2 interface.  Of course, mirao 52-e is CE marked and conforms to international electromagnetic and electrical safety standards.

The new electronic unit provides improved environmental isolation which contributes to enhancing the mirror unit’s overall temporal behavior.  It equally enables users to apply up to 1V to each of the mirror unit’s actuators with a total maximum applied voltage of 25V, up from 18V in the previous version.  Finally, the new electronic unit offers improved temperature protection and provides a trigger output to facilitate synchronization with other devices via a TTL signal.

The other major enhancement to the mirao 52-e is an all-new Application Programming Interface (API) that was painstakingly developed to provide easy access to mirao’s powerful wavefront correction abilities and ensure backwards compatibility as the product continues to evolve.  The API includes a complete, timesaving collection of high-level functions so that users can quickly develop feature-rich applications without having to rewrite driver libraries on their own.  The software has been optimized so that users can easily store the voltage commands that are frequently used in active memory in order to further improve the device’s temporal response. Thanks to its strict compliance to the ANSI C standards, the API library can be used in a large number of development environments.

One of the API’s key programming innovations is the “Apply Smooth Command” option.  Specially designed for users working with high-temporal frequency aberrations, this new function enables users to effect gradual, rather than abrupt, changes to the actuator voltages.  This option helps users to minimize the risk of introducing parasite vibrations when working with high temporal frequencies.  The API equally includes error message management that processes information sent back from the electronic unit so that users can better control their adaptive optics loop.
