Model: IT-300
Manufacturer: JEOL
Area: MiNaLab SEM-room

Technology Description:

The Scanning Electron Microscopy (SEM) instrument at MiNaLab is suitable for high-resolution imaging, semi-quantitative X-ray microanalysis, as well as cathodoluminescence imaging and spectral analyses. The microscope’s low vacuum capability allows observation of non-conductive samples in their natural state, without the need for metal coating. In situ experiments can be performed with the use of a cooling/heating stage at the temperature range -185 °C to 200 °C.


Secondary electron (SE) detector (Everhardt-Thornley, E-T).

Backscattered electron (BSE) detector (Si P-N junction semiconductor detector).

Thermo Scientific Ultra Dry silicon drift X-ray detector (SSD) 60 mm2 with Norvar light element window and energy resolution (MnKα FWHM) at 127.8 eV, running on a Noran System 7 (Pathfinder software) for semi-quantitative elemental analysis and mapping.

Delmic SPARC Cathodoluminescence system, running on the ODEMIS software. Booking of the cathodoluminescence system to be done through the "Cathodoluminescence" instrument in LIMS.
