GRINTECH GMBH

Their core work

GrinTech is a Jena-based SME specializing in gradient-index (GRIN) micro-optics and miniaturized optical components used in biomedical imaging and diagnostics. They manufacture precision lens systems that enable endoscopic and point-of-care optical instruments — the kind of components that make it physically possible to bring Raman spectroscopy, optical coherence tomography, and multimodal imaging into clinical settings. Their H2020 participation centers on supplying specialized optical hardware to cancer diagnosis projects, particularly for gastrointestinal and bladder cancer detection. Located in Germany's historic optics cluster (Jena), they bridge the gap between photonics manufacturing and clinical application.

What they specialise in

How they've shifted over time

GrinTech's earliest H2020 involvement (MIB, 2016) focused on endoscopic biophotonic imaging for bladder cancer — a single-modality, single-application project. By 2020, their two newer projects (PROSCOPE and PHAST) both involve combining multiple optical techniques — Raman spectroscopy, OCT, two-photon microscopy, diffuse optics — into integrated diagnostic platforms for broader cancer applications. The trajectory is clear: from component supplier for single imaging modalities toward enabling complex multimodal diagnostic instruments.

GrinTech is moving toward integrated multi-technique optical platforms for clinical cancer diagnostics, making them increasingly relevant for projects combining photonics with point-of-care medicine.

How they like to work

GrinTech consistently participates as a specialist partner rather than leading consortia — all three projects have them in a participant role, which is typical for an SME providing specific hardware components. With 28 unique partners across 9 countries from just 3 projects, they work in large, diverse consortia (averaging ~10 partners per project). This pattern suggests they are a trusted component supplier that research-led consortia recruit when they need precision optics expertise.

GrinTech has collaborated with 28 unique partners across 9 countries through just 3 projects, indicating involvement in large research consortia spanning multiple European nations. Their network is concentrated in the medical photonics research community, connecting clinical partners, university labs, and instrumentation developers.

What sets them apart

GrinTech occupies a niche that few European SMEs can match: precision GRIN micro-optics manufacturing with direct experience integrating into clinical diagnostic instruments. Their Jena location places them at the heart of Germany's photonics ecosystem, with access to suppliers, talent, and research infrastructure that a standalone optics startup would lack. For any consortium building a biomedical imaging instrument that needs to be small enough for endoscopic or point-of-care use, GrinTech offers proven miniaturization expertise validated across multiple EU projects.

Highlights from their portfolio

• PROSCOPE
  Largest funding (EUR 539K) and most technically ambitious — combining four optical modalities (OCT, Raman, two-photon, conventional imaging) into a single colorectal cancer diagnostic instrument.
• PHAST
  MSCA training network connecting photonics to healthcare across multiple cancer types, positioning GrinTech as a training host for next-generation biophotonics researchers.
• MIB
  GrinTech's entry into H2020 biophotonics — endoscopic imaging for bladder cancer, establishing their role as a go-to micro-optics partner in medical photonics consortia.
