3D Glass Microfluidics with Integrated Optical Fibre Connections

Lambda Glass Solutions combines three-dimensional fluid routing and optical interfaces in custom fused silica components. The structures incorporate fluid channels, precise fibre positioning directly at the channel and integrated fluid connections. Designs range from flat microfluidic chips to three-dimensional fluidic blocks.

Integrated Optical Fibres for Inline Analysis

The fibre connections allow light to be coupled directly into the fluid channel and optical signals to be read out. This enables the development of compact measurement cells for inline analysis, including absorption, fluorescence and Raman measurements. Fluid routing and optical measurement interfaces are combined in a single component.

Selective Laser-Induced Etching for Custom Microfluidic Components

Lambda Glass Solutions uses selective laser-induced etching (SLE) to manufacture three-dimensional channels, fibre holders and connection geometries in fused silica. Monolithic fluidic structures reduce the need for joined individual parts. Channel routing, the measurement region and interfaces are tailored to the application, allowing fluid routing and optical fibre integration to be considered together during component design.

Lambda Glass Solutions will present the technology at COMPAMED 2026 in Düsseldorf, November 16–19.
