Precise microstructures in fused silica – when off-the-shelf isn’t an option.

Looking for a solution to create extremely fine structures in quartz glass? Using our SLE technology, we realize complex 3D geometries with resolutions below 10 µm – ideal for applications where conventional methods reach their limits.

Solutions for complex requirements

Our SLE technology (Selective Laser-induced Etching) enables true 3D microstructures directly within the volume of fused silica. Combined with CNC machining, flame processing, and polishing, we manufacture highly functional components – precise, durable, and designed for industrial use.

  • Wafer Handling

    We develop 3D-modulated contact surfaces that enable reliable wafer handling without adhesion – even for surface structures down to 200 µm. Our fused silica pins are sharper than a needle and ensure accurate, gentle contact.

  • 3D Microfluidics

    We manufacture real 3D microfluidic channels inside fused silica – including complex nozzle shapes, cross channels, and direct fiber integration. Compact, precise, and permanently stable.

  • Fluid and Gas Handling

    We create high-precision fluid and gas channels with tight tolerances. Suitable for micro nozzles, injectors, and fiber feedthroughs – with bore diameters down to 10 µm and custom geometries.

  • Real 3D Coating Heads

    We produce fully integrated 3D coating heads with freely designable gas channels – no drilling, no bonding. ±5 µm repeatability, uniform gas distribution across the wafer surface.

  • Real Fiber Accessories

    We produce fiber-compatible microstructures like ferrules, M1 threads, and borehole arrays – with 126 µm or 150 µm diameters. Ideal for photonics, fiber optics, and sensing applications.

  • Electronics Packaging and TGVs

    We enable ultra-dense packaging in fused silica – including 3D pockets with 5 µm resolution, 15 µm bore arrays, and helical vias. Perfect for SiP, HDI, optoelectronics, and microelectronics.

  • Micrometer 3D Designs

    We realize functional 3D geometries in glass with sub-10 µm resolution. Freeform structures, pockets, and surface patterns – where complexity and precision are essential.

  • Real 3D Micromechanics

    We build integrated 3D micromechanical elements directly in fused silica – without assembly, bonding, or separate parts. Mechanical functions in a single solid block.

We are Lambda Glass Solutions

When microstructures in glass need to be realized with high precision, repeatability, and economic efficiency, standard processes are not enough. That’s why we at Lambda Glass have developed a method that combines laser-based 3D structuring (SLE) with proven glass processing techniques like CNC, flame, and polishing.

This allows us to create functional structures directly within the glass – without bonding, without assembly, and exactly tailored to the customer’s requirements. The method is flexible, fast to implement, and suitable for series production. Whether microchannels, optical interfaces, or complex 3D geometries – we don’t just deliver parts, we deliver solutions that work technically and economically.
