Unlocking new regimes in light-matter interaction

Harness the extraordinary power of optical microcavities with our tailored solutions - from individual micromirrors to complete cryogenic platforms and analytical tools for researchers, developers and engineers in both academia and industry. 

Compact microcavity platform enabling vibration-resistant, high-finesse cavity experiments with turnkey control and flexible signal collection.

Microcavity platforms

Qlibri CP-Pro and CP-Compact

A highly stable scanning microcavity platform for closed-cycle cryostats, enabling strong light-matter coupling in solid state systems. Our flexible, open-cavity design supports fast, efficient sampling of thousands of emitters across a range of wavelengths and emitter types.

Resonator-enhanced absorption microscope for quantitative imaging of nanoscale particles, thin films, and single defects with 0.1 ppm sensitivity.

Absorption microscopes

Qlibri Nano and OCA

Our fast, label-free scanning microscope enables spatial-, spectral-, and time-resolved detection and characterization of individual nanoscale particles, thin films, and defects. A 1000× increased absorption sensitivity over conventional techniques allows for quantitative analysis of features previously undetectable.

Fiber-based microcavity mirrors with laser-machined concave profiles for compact, alignment-free Fabry–Pérot cavities in quantum and nanophotonic applications.

Microcavity mirrors

High-reflectivity, precision-engineered microscopic mirrors for seamless integration into cavity-based experiments. Ideal for ion traps, cold atoms, single-photon sources, enhanced light–matter interaction, gas sensing, filtering, and more. Developed by pioneers in fiber-cavity technology with over a decade of experience in high-finesse system.
