Cathodo-luminescence detector : the ultimate solution.

Panchromatic and RGB Cathodoluminescence (CL) intensity detection

Learn more about your sample in just a few moments with the entry-level SEM- integrated cathodoluminescence (CL) detector JOLT.

Key benefits.

Choose your version

Perform panchromatic or RGB CL detection.

Start imaging quickly

Operate the system easily.

Combine with other detectors

Harness all data available by combining CL with other SEM techniques.

Acquire (RGB) intensity maps

Easily obtain information about the intensity and colour of CL emission.



The JOLT is an entry- level CL-intensity detector based on state-of-the-art solid state detectors.

Delmic offers JOLT in two variations: a panchromatic version and an RGB (coloured CL) version. JOLT can be easily mounted on a single SEM vacuum port and is controlled by a software app in combination with the SEM control computer.

It is a great addition for correlative imaging with other SEM-based detectors such as backscattered electron imaging and energy-dispersive x-ray imaging, capable of providing more insight into your sample’s properties. It is perfect for those who are working with and studying geological samples, semiconductors and other materials.
