Webinar Announcement: The Allalin – From Experimental Struggle to a New Standard in Nanoscale Spectroscopy

Attolight is pleased to announce an upcoming webinar titled “The Allalin: From Experimental Struggle to a New Standard in Nanoscale Spectroscopy”, presented by Dr. Christian Monachon, Product Manager & Head of Applications at Attolight AG (Switzerland).

This session will explore the development journey of the Allalin platform, originating from the challenges of early home-built time-resolved cathodoluminescence (TR-CL) systems. What began as a time-consuming experimental struggle requiring manual optical alignment has evolved into a fully integrated, spectroscopy-first Scanning Electron Microscopy (SEM) platform designed for reliable and quantitative nanoscale characterization.

The webinar will highlight the key design principles behind the Allalin system, including a wide, stable 300 µm field of view, aberration-corrected optics, and integrated cathodoluminescence (CL), photoluminescence (PL), and Raman capabilities. These innovations enable robust and reproducible measurements without alignment constraints, ensuring consistent detection efficiency across the entire scan area.

A range of practical applications will be presented, spanning both academic and industrial research. These include dopant concentration mapping in GaN, defect quantification in photonic devices where repeatability and throughput are critical, as well as time-resolved CL studies at cryogenic temperatures (<6 K) on challenging, charge-sensitive materials such as DUV emitters and polymers.

This webinar is intended for researchers and engineers working in nanophotonics, semiconductor science, and advanced materials who are interested in high-precision nanoscale spectroscopy and advanced SEM-based optical characterization workflows.
