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.
The Delta 7-10 is a transmissive wavefront modulator delivered with dedicated driving electronics and control software.
It is designed for demanding wavefront shaping applications, where neither size nor performance can be compromised.
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 of less than λ/40 independent of the DPP orientation
Polarization-independent
Wavefront modulation independent of the light polarization for maximized efficiency
