In line with The FrontSurfer and The LightPipes  packages for WF sensing and scalar wave optics, we produce a wide range of custom software.

Zernike Commander is a simple yet useful software tool suitable for education, real-time aberration visualization as well as for generation of test Hartmann image patterns. The software accepts an wavefront aberration described in the form of Zernike coefficients as well as parameters of Schack-Hartmann  wavefront sensor as its input and produces the following graphical results: 3D representation of wavefront phase, interference pattern, far-field intensity distribution, Hartmann pattern, overview of Zernike modes.

The wavefront analysis and control system  FrontSurfer is the most inexpensive Hartmann-Shack sensor on the market. Nevertheless, the system is very universal and can be used for:

  • Optical shop testing of transmissive and reflective optics: lenses, mirrors, lens assemblies, collimators, etc. The measurement precision can reach λ/100 rms.
  • Real-time display of low-order aberrations (tip/tilt, defocus, coma, astigmatism) in the “Alignment mode”.
  • Real-time control and compensation of wavefront aberrations in combination with OKO deformable mirrors. With most OKO mirrors the low-order Zernike modes can be corrected with a precision of λ/40 and better.

OKO extends the capabilities of modern imaging systems by introducing purely software-based  system for image stabilization, object tracking, frame integration and multi-frame deconvolution.  It offers an almost real time  enhanced imaging through turbulent and wavy media. The system works with live video sequences fed via DirectShow (webcam) interface, or from   a  CMOS or CCD camera. To get the impression, please watch the recordings below, better seen in a full-frame mode. Feel free to contact us with any technical question, or for an  offer. The basic configuration of the system is available from stock.

BeamTuner is a simple to use Windows application for compensating of a static aberration in an optical system with a deformable mirror (DM). The software doesn't require any wavefront sensor, as it uses the focal spot image as the feedback. During  optimization,   the BeamTuner tries to find the best set of DM controls to minimise the focal spot. The set of control signals can be saved to be used later or in other applications.

LightPipes is a set of software tools for simulation of propagation, diffraction and interference of coherent light. Algorithms are based on  the scalar theory of diffraction. The toolbox includes  spectral, FFT-based and finite-difference based  propagation models. Special tools have been  developedd for the propagation through lenses with coordinate transforms, simulation of any combination of Zernike aberrations, mode analysis in laser resonators, interferometers, inverse problems, waveguides and propagation in media with non-uniform distribution of refraction index.

OKO introduces Zemax DLLs  to facilitate realistic simulation of optical systems that include deformable mirrors produced by OKO.  There are two separate libraries for two mirror classes: one is for Micromachined Deformable Mirrors (MMDM) and the other is for Piezoactuated Deformable Mirors (PDM). The libraries are implemented in the form of User Defined Surface (UDS) DLLs for Zemax and can be used in any Zemax model and suitable for every way of analysis. We provide those UDS to facilitate design by customers of their systems utilizing our deformable mirrors. Thus it is possible to evaluate parameters of a particular model of deformable mirror and assess it applicability to some particular application and setup. Also it makes easier to choose between several available mirror models. The configuration data is provided for all round MMDM and PDM models ever produced by Flexible Optical B.V.  Detailed User's manuals are available for the  MMDM version and for the PDM version.  The software is developed by Flexible Optical B.V. in collaboration with Fraunhofer Institute for Laser Technology ILT/ Chair for Technology of Optical Systems TOS RWTH Aachen University. Part of the development was carried out within the framework of UltraSURFACE European project (H2020-ICT-2015, Project no. 687222).
