Brand: GATAN Name and Model: ChromaCL2 Cathodoluminescence System

Manufacturer: GATAN Company Distributor: Obotong Co., Ltd

Product Overview:

Product Function Introduction:

Real time color cathodoluminescence imaging plays an important role in mineral analysis laboratories. ChromaCL2 provides new assistance in various new and old issues, from oil and gas exploration to geochronology and mineral growth research.

ChromaCL2 is Gatan's second-generation real-time color cathodoluminescence imaging system. It has efficient optical acquisition and dispersion capabilities, and uses array photomultiplier tubes to achieve high gain light detection capability. Real time mixing of photon pulse signals into real-time color cathodoluminescence images using DigitalMicrograph software.

Colored CL images can indicate changes in mineral composition, including the distribution of phases and trace elements, making it easy to observe chemical imprints, overgrowth, growth zones, internal healing cracks, and more. And for ChromaCL2, all of these can be fully revealed with just one electron beam scan.

Main technical features of the product:

1. Real time color imaging - a single scan can obtain color CL images to quickly and clearly interpret data;

2. Parallel detection of all wavelengths - a single scan can obtain color CL images to quickly and clearly interpret data;

3. Collecting mirror for diamond processing - collecting CL signals at large solid angles to improve efficiency and spatial resolution;

4. Fixed gain, integrated electronic system - easily collect data with just a click of the mouse;

5. Scalability - up to a range of 150mm;

6. Fixed insertion position - simply set to optimize optical acquisition;

7. Dynamic range - pixel intensity can reach up to 600000 counts per second

8. Real time color and purple imaging - sensitivity extended to the purple range

9. Multi field stitching - using automatic montage software to obtain a large field of view;

10. Integrated BSED - simultaneous acquisition of secondary electrons, backscattered electrons, and cathodoluminescence signals;

11. Eliminating phosphorescence phenomenon - imaging of samples containing hydrochloride salts;

12. Computer platform - Windows 7, 32- or 64 bit operating system

Main technical parameters of the product:
