COXEM Options & Accessories

Low Vacuum System

COXEM offer a Low Vacuum System for imaging non-conductive samples without coating during sample preparation. Low vacuum operation can be used to image biological samples or insulating materials in electronics.

Low vacuum operation is used with the BSE detector for imaging, and is effective at low magnifications. The possible vacuum range is 100pa to 1pa.

Cool Stage

The COXEM Cool Stage is a temperature-controlled sample stage for COXEM Scanning Electron Microscopes systems. A cool stage is used in electron microscopy to chill biological or other wet specimens, preserving surface features and improving imaging ability. Samples can be cooled to -25°C, and also heated up to 50°C. Temperature is controlled digitally.

STEM Detector

Both full size and benchtop Scanning Electron Microscope (SEM) systems from COXEM can be expanded to support Scanning Transmission Electron Microscopy (STEM) capabilities with the COXEM STEM Detector. This allows a COXEM SEM to handle multiple imaging applications outside of standard SEM imaging tasks.

COXEM's STEM Detector is mounted inside the SEM chamber, and can be retracted and tilted 90° out of the field of view to allow regular SEM functions. Support for the STEM Detector is fully integrated into the NanoStation operating software for COXEM SEMs, with the same simple and easy operation.

True TEM Detector

Most STEM modules differ from the true TEM principle, and use a platinum mirror and the SEM's SE detector to collect an image. The COXEM STEM Detector uses a true TEM detector beneath the TEM sample.

The STEM Detector supports both Bright Field (BF) and Dark Field (DF) imaging.

TEM Grid Holder

A specially designed TEM grid holder is included with the STEM detector, which mounts onto the SEM stage. Up to 4 standard TEM grids can be accommodated in the holder. The holder has been designed to allow EDS analysis without the need for separate adjustment.

SPT-20 Ion Sputter Coater

SPT-20 Ion Sputter Coater

The SPT-20 Ion Sputter Coater is a simple to use, compact and cost-effective solution for sputter coating non-conductive specimens in SEM sample preparation. Features a user friendly touch screen interface, and supports multiple metal types.

CP-8000 Ion Mill Cross Section Polisher

CP-8000 Ion Mill Cross Section Polisher

The CP-8000 Ion Mill Cross Section Polisher gives a perfect finish for SEM sample preparation. Using an argon ion beam, the CP-8000 gently removes material from a sample's surface without deforming or smearing. Easy to use with a touch screen interface.
