mirao™ 52-e Electromagnetic Deformable Mirror

mirao 52-e is a unique wavefront shaping technology that combines unparalleled stroke and precision with low power consumption and USB2 connectivity to meet the needs of today’s most demanding applications. Key features include:

  • ±50 µm stroke (tilt p/v)
  • 15mm pupil with 52 actuators
  • exceptional optical quality (10 nm rms)
  • surprising precision (20 nm rms)
  • virtually no hysteresis (<2%)
  • near perfect linearity (>95%)
  • TRIG-OUT for TTL synchronization
  • USB2 connectivity
  • ANSI-based Application Programming Interface (API) compatible with standard programming environments
  • Fully IEC 61010 & 1236 compliant (electrical safety and electromagnetic compatibility)

miraomirao is a unique technology that overcomes many of the barriers that limited deformable mirror performance in the past. By using electromagnetic energy to deform the mirror’s surface up to ±50 µm (tilt p/v), it outperforms other commercially available mirrors in applications where severe aberrations need to be corrected. Even up to the Zernike 6th order with extreme precision.

In addition to its excellent optical quality, high linearity and lack of hysteresis, the fact that mirao functions with almost any beam wavelength and intensity makes it ideal for a wide range of applications. mirao 52-e’s new, ultra-compact electronic unit connects to your PC via a stand USB2 port, and offers improved temporal performance and stability. What’s more, we’ve added 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. 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. Thanks to its strict compliance to the ANSI C standards, the API library can be used in a large number of development environments.
