A Complete, Ultrafast Cathodoluminescence System

Picosecond pulsed SEM with spectral and time-resolved CL

We provide you with a complete time-resolved cathodoluminescence set-up consisting of our ultrafast pulsed scanning electron microscope and a time-resolved cathodoluminescence detection line. With the full system, you are ready to measure carrier dynamics in nanostructures and more.

Ultrafast Pulsed SEM

The pulsed SEM is Attolight's core product. It is the only pulsed SEM on the market achieving 10 ps temporal resolution. This SEM also replaces beam blanking technology since it assures beam stability down to 50 nm.

Technical specifications

Probe current 10 pA (corresponds to 1 electron/pulse
Resolution in secondary
electron mode		 50 nm
Acceleration voltage 2 - 20 kV
Pulse temporal width 10 ps
Electron repetition rate 80 MHz (12 ns between each pulse)

CW Cathodoluminescence Universal Extension (CLUE)

The CW (Continuous Wave) Cathodoluminescence Universal Extension (CLUE) adds enhanced analytical capabilities to scanning electron microscopes, providing spatial resolution of an electron probe. Full user control of electron mapping offers polychromatic and monochromatic cathodoluminescence images, as well as advanced mapping.

The CLUE was developed by HORIBA Jobin Yvon and offers outstanding optical and spectroscopic performances. It integrates easily within most SEMs, for fast spectral acquisition when working in CCD mode or high resolution spectral acquisition when working with a photomultiplier tube.

Time-Resolved Cathodoluminescence (TRCL) Extension

The Time-Resolved Cathodoluminescence (TRCL) Extension is based on HORIBA Jobin Yvon's CLUE system and includes a multichannel ultrafast photon detector (Hamamatsu streak camera). It was developed to ensure the best optical quality while allowing you to work with ultrafast cathodoluminescence signals.

Given an excitation point on the sample, the TRCL Extension yields spectrally and temporally resolved cathodoluminescence images.

Technical specifications

Detectable wavelength 210 - 1500 nm
Temporal resolution 2 ps
Temporal range 10 ps - 2 ns
Stand-alone optically pumped electron source 10 ps
