Attolight manufactures the leading cathodoluminescence (CL) microscopes and accessories on the market. These systems are used for a range of applications, including:
- Micro-LED characterization
- Defect Visualization and Counting in Optoelectronic Materials
- Power Electronics
- Photovoltaic Materials
- Defects in Thin Film Battery Materials
- Semiconducting Diamond
Three types of systems are available:
Allalin – Research-grade SEM-CL Tool
The Allalin is a nanometer resolution spectroscopy instrument, based on quantitative CL that integrates a CL detection tool and a scanning electron microscope (SEM) into one tool.
Some of the benefits of the Allalin include:
Zero alignment needed for CL detection
Large field of view (300 microns) without moving the sample
Simultaneous generation of CL and secondary electron (SE) images
Low-temperature operation to 10K
Upgradable to Chronos time-resolved CL with 10 ps time resolution.

The Allalin SEM-CL Tool
Attolight has developed the first Quantitative CL system that allows for the comparison of spectra from different regions and samples to representative quantitative differences in your sample. On Attolight systems, differences of this type are reflective of differences in the material. Using traditional CL techniques, these differences can often be due to alignment issues related to the parabolic mirror used in these systems.
Säntis 300 – Full Wafer CL Measurement Tool
The Säntis 300 system has been designed for fully automated CL measurements and control of on wafers up to 300mm. The system is available with a range of options that allow for sample turnaround and process automation.

Chronos – Time-Resolved CL Tool
The Chronos is a time-resolved CL tool that builds on the Allalin quantitative CL system. The system can provide time-resolutions of up to 10 ps with full spectral data reported at each point.
