MIRAO 52E

In addition to its excellent optical quality, high linearity and lack of hysteresis, Mirao 52e can be used in a wide spectral range and has a high intensity threshold, which also makes this deformable mirror a great candidate for various beam shaping applications.

Mirao’s electronic controller connects to PC via USB port. There is also a trigger output available to facilitate synchronization with other devices via TTL signal. Together with Mirao 52e we offer a free Application Programming Interface (API) which was developed to provide easy access to Mirao’s powerful wavefront correction abilities. In addition to that we developed a complete Software Development Kit (SDK), which includes a time-saving collection of high-level functions so that users can quickly develop their own software. We offer the SDK in C, C++, LabView and Python environments.

For safer operation of the deformable mirror as an option we are also offering dust-proof protective case around the mirror together with an AR coated window in front of the mirror membrane.

MIRAO 52ES

LARGE-STROKE DEFORMABLE MIRROR OPTIMIZED FOR OPEN-LOOP OPERATION

The line of Mirao deformable mirrors provides an exceptionally large stroke and high precision combined with low power consumption and USB connectivity in order to meet the needs of today’s most demanding applications. Mirao 52es incorporates a unique technology that uses 52 electromagnetic actuators, enough to precisely correct up to the 6th order Zernike modes. This mirror also provides an exceptional 50μm PV deformation amplitude, which makes this mirror especially useful in various bio imaging and microscopy applications where large-amplitude aberrations need to be corrected.

Many applications of adaptive optics are using a deformable mirror to create a precise wavefront shape, which is then kept fixed during operation of the optical setup (in microscopy, beam shaping etc.). As soon as a precise wavefront/PSF shape needs to be maintained during long term experiments – Mirao 52es is the perfect choice.

The exceptional feature of Mirao 52es deformable mirror is its long-term stability in an open-loop mode. As it is shown in the graph above, the difference of the generated wavefront to the target wavefront remains within less than 10nm RMS for more than 12 hours (green trace), as compared to a standard Mirao 52e deformable mirror (blue trace). The stability of the mirror is also illustrated by the image sequence on the right: on a microscope equipped with Mirao 52es deformable mirror we imaged the PSF over the course of three days and changes of the PSF were negligible.

Mirao 52e electromagnetic deformable mirror offers exceptionally large stroke and high optical quality combined with low power consumption and USB2 connectivity. This provides advanced capabilities in terms of wavefront correction therefore Mirao 52e electromagnetic deformable mirror is best suited for applications requiring high-quality closed loop correction, such as bio-imaging, ophthalmology, microscopy, beam shaping etc.

key features include;

  • ±50 µm stroke (tilt p/v)
  • 15mm pupil with 52 actuators
  • exceptional surface quality (<10 nm rms active flat)
  • virtually no hysteresis (<2%)
  • near perfect linearity (>95%)
  • compatible with open-loop control
  • USB2 connectivity
