The scanning electron microscopy technique is versatile and non-destructive, it reveals the morphology and the composition of a lot of materials. The ZEISS SUPRA™ 40 is a SEM-FEG capable of high quality semples imaging. Perfect for investigateing nanosystems, it offers high stability and a large (130 mm) versatile specimen holder. Meanwhile, the GEMINI FESEM column utilised on the SUPRA™ 40 has an extremely low magnetic field outside the objective lens enabling investigation of magnetic materials and devices. A field-emission cathode in the electron gun provides improved spatial resolution and minimized sample charging/damage.
