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.

Fused silica component with 3D-modulated contact surfaces for adhesion-free wafer handling

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 microchannels in fused silica with integrated fiber access for microfluidic applications

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.

High-precision microchannels and bores in fused silica for liquid and gas handling

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.

Fused silica 3D coating head with freely designed channel structures for homogeneous gas distribution

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.

Fused silica fiber guides and optical interfaces with ferrules and hole arrays

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.

Fused silica with helical through-glass vias (TGVs) and dense hole arrays for 3D packaging

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.

Custom freeform microstructures in fused silica with feature sizes below 10 µm

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.

Functional micromechanics manufactured directly inside the fused silica block, assembly-free

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.
