KEY FEATURES
Complex wavefront modulation
63 electrodes enabling replication of up to the 7th radial order of Zernike polynomials (>35 modes) with high fidelity
Straightforward system integration
Compact housing compatible with standard 30 mm cage systems by rods, lens tubes, and post assemblies
Linear & hysteresis-free response
Electrostatic actuation suited for open-loop wavefront control
Remarkable optical quality
Active best flat with an induced RMS wavefront error ofless than λ/40
Polarization-independent
Wavefront modulation independent of the light
polarization for maximized efficiency
​
The Delta 7 is based on the Deformable Phase
Plate (DPP) technology, exclusively developed by
Phaseform GmbH. DPP is composed of a fluidic
chamber, enclosed by a thin membrane, which is
deformed by electrostatic force. The force is
generated by a 2D array of transparent electrodes
embedded within the optical aperture of the DPP.
The sophisticated optofluidic design of the 10 mm
aperture DPP enables gravity-neutral performance
for orientation-independent, high-quality wavefront
modulation.
