AttolightAttolight manufactures the leading cathodoluminescence (CL) microscopes and accessories on the market.  These systems have been used for a range of applications, including:

  • Micro-LED characterization
  • Defect Visualization and Counting in Optoelectronic Materials
  • GaN for Power Electronics
  • Photovoltaic Materials
  • Defects in Thin Film Battery Materials
  • Semiconducting Diamond

EAG Laboratories and Attolight Announce Partnership

Two types of systems are available:

Allalin SEM-CL

The Allalin is a nanometer resolution spectroscopy instrument, based on a disruptive technology known as quantitative cathodoluminescence that integrates a light microscope and a scanning electron microscope (SEM) into one tool.

For more details on the Allalin system, please see the Attolight product page:

Quantitative Cathodoluminescence

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.

300 Micron Field-of-View

Attolight’s SEM-CL tools provide for a 300 micron field of view where CL spectra data is obtained without moving the sample.

Cryogenic Nanopositioning Stage

The Attolight system can be configured with a cryogenic nanopositioning stage that provides temperature control down to 8K with 1 nm accuracy and pivot-point precision that allows you to define a pivot point and have the same rotated about that point.

Chronos Time-Resolved Cathodoluminescence

Picosecond time-resolved cathodoluminescence microscope

The Chronos is a variable temperature time-resolved nanometer resolution spectroscopy instrument that builds on the Allalin quantitative CL system. In continuous operation mode, the Chronos works like the Allalin system using the same high current density Schottky field emission gun.

Säntis 300

Full wafer cathodoluminescence microscope

The Säntis 300 system has been designed for fully automated control of 150, 200 and 300mm wafers.
