Delmic JOLT

Product Overview

JOLT is a foundational cathodoluminescence detection system equipped with a highly sensitive multi-pixel photon counter array for either color filtered or panchromatic CL intensity acquisition. JOLT prioritizes easy accessibility for users, ensuring rapid analysis sessions with intensity maps of all kinds of samples ranging from rocks in geology, tiles in ceramics, and electronic components in the semiconductor industry.

Simple and Fast

JOLT takes the core aspects of CL intensity mapping and distills them into two versions for entry-level and effective CL imaging.

Easy Integration

All it takes is a single vacuum port. JOLT is compatible with all kinds of SEMs and can begin collecting CL emission as soon as it’s connected.

JOLT Features

The JOLT is controlled through a user interface displayed on the SEM computer, offering a range of output settings that users can alter for image optimization. Because the JOLT is completely preconfigured and calibrated, manual alignment of the instrument prior to active use is unnecessary.

Expand the suite of SEM detectors by combining CL emission with electron signals such as backscattered and secondary electrons (BSD and SED) and the X-ray signals of energy dispersive spectroscopy (EDS), wave dispersive spectroscopy (WDS), and X-ray fluorescence (XRF).

Use JOLT – the fastest and simplest CL system – to gather data pertinent to:

  • Crystal zonation in zircons
  • Defect densities in electronics
