Welcome to Flexible Optical B.V.!

Adaptive mirrors from OKO

Flexible Optical B.V. (OKO Tech) is a small Dutch business operating in the field of research and application-oriented development of laser and high resolution imaging adaptive optics. From its foundation in 1997, OKO offers high-quality deformable mirrors featuring extremely smooth surface with HR metal and dielectric coatings suitable for most demanding imaging and high power laser applications.

79-ch 15 mm MMDM with optimised actuator geometry

OKO introduces a 79-channel 15 mm membrane deformable mirror MI4-v1. The device features novel geometry of actuators, specially designed for the best approximation of the low-order Zernike polynomials in the working aperture of 8.7 mm.

The mirror is commercialision of our research and development activities funded by ECSEL in terms of MADEin4 project.

MADEin4

Flexible Optical B.V. is a member of MADEin4 project, a consortium that develops next generation metrology tools, machine learning methods and applications in support of Industry 4.0 high volume manufacturing in the semiconductor and automotive manufacturing industries.

Simulation of OKO DMs in Zemax

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).

96-ch DM powered and controlled by a single USB link

OKO introduces a 96-channel 25.4 mm membrane deformable mirror with embedded control electronics. The device has sturdy compact enclosure with dimensions of 90 x 90 x 43 mm (volume is about 0.35 l), it is powered and controlled by a single USB link. The mirror features full deflection of 19 μm and maximum update rate of 2 kHz. With the development of this DM, OKO makes possible to build a complete AO system that does not require any external power supply, as all the power for the WF sensor and the DM is provided through available USB ports of the control computer, with total power consumption for a complete 96-ch AO system not exceeding 5 W.

Datasheet

Zernike Commander: simulation and visualization

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.

Deformable mirrors for high power lasers

OKO introduces a line of laser deformable mirrors (DM). These DMs feature highly reflective coatings with reflectivity of up to 99.998%, for the most frequently used laser wavelengths of 1060 nm, 530 nm, and any other wavelength in the range of 250 to 2500 nm. The standard DMs have light aperture of 30mm and 50mm, and can have 18,19 and 37 actuators (30 and 50mm diameter), and also 59, 69, 79 and 109 actuators (50mm diameter). Mirrors can work with continuous laser loads of up to tens of kW. The power handling ability is enchanced by active cooling of the mirror structure with embedded cooling fan.
