Optics Manufactured a Nanopore at a Time
FemtoEtch™ nanostructuring embeds polarization control directly into fused silica — geometries impossible with cut crystal assemblies.
Product Family
Four product lines, one fabrication platform. Browse by product to see where each one excels, then send us your specification.
Radial & azimuthal beams from a single element
Vortex plate converters transform linear polarization into radial or azimuthal states with monolithic fused-silica reliability — the workhorse element for advanced beam shaping.
Radial polarization improves cutting and drilling efficiency in metals by up to a factor of two.
Azimuthal beams create the doughnut-shaped focal spots behind STED and related techniques.
Structured polarization enables stronger, more selective optical tweezers.

Built for the
Hardest Optical Jobs
Where conventional optics hit a wall — extreme optical load, UV/DUV wavelengths, geometrical-phase control — nanostructured fused silica is the only material that answers.
Laser-Driven Fusion Energy
No conventional optic can offer geometrical-phase (polarization) control and withstand the optical load of a fusion driver. These elements raise beam efficiency — bringing the world one step closer to clean energy.
Microscopy & Semiconductor Metrology
Higher resolution means moving to UV and DUV, where only the right material survives: nonlinear crystals and polymers absorb heavily in the UV, fused silica does not. SPhotonix X-prisms are a unique solution — tailorable to the UV/DUV region for best-in-class spectral performance.
Micromachining
Higher aspect ratios in drilling and smoother scribing — outcomes only geometrical-phase elements can deliver.
Precision.Purity.Performance.
20 nm Nanopore Precision
FemtoEtch™ steers polarization and birefringence of every individual nanopore – precision no mechanical polishing can reach.
Monolithic Fused Silica
Optical function embedded inside a single substrate: no cemented interfaces, no misalignment, no delamination.
Lower Scattering
Nanostructured elements deliver higher imaging resolution and contrast than assembled crystal optics.
Arbitrary Geometries
Software-defined fabrication produces polarization patterns and gradients impossible to grind or cut.
Extreme Environments
Fused silica survives high-power beams, UV exposure and thermal cycling — built for laser fusion and space optics.
Design
Polarization function is specified in software – retardance and azimuth per nanopore – then simulated before a single pulse fires.
Fabricate
FemtoEtch™ writes trillions of nanopores inside the fused-silica blank, embedding the optic within the material itself.
Verify
Every element is mapped by polarised metrology and shipped with its measured performance — not a datasheet average.
“Nanostructured optics let us shape polarization in ways crystal assemblies never could. For microscopy, that translates directly into resolution.”
