Used PHILIPS / FEI Quanta 250 FEG #293768755 for sale

PHILIPS / FEI Quanta 250 FEG is a versatile and powerful scanning electron microscope (SEM) used in a wide range of research, industrial, and educational applications. It features a field-emission gun source with a unique, dual-segmented detector allowing for simultaneous imaging of samples at high magnification and low signal-to-noise ratio in a wide range of applications. FEI Quanta 250 FEG uses a low-voltage, field-emission gun (FEG) source which provides an exceptionally short electron beam, with an electron energy of 3 to 30 kV, an extremely small spot size of less than 1.0 nm and a high beam current of up to 0.5 nA. This enables imaging of relatively large samples at very high resolution. The sample can be positioned precisely and tracked with the in-built motorized stage. PHILIPS Quanta 250 FEG features a dual-segmented detector configuration with a semi-transmission detector, which is used to produce bright and contrasty images, and a secondary backscattered electron (BSE) detector, which yields high depth of focus, excellent depth resolution and magnification control. This combination enhances contrast and allows for visualization of features as small as 5 nanometers in size. Quanta 250 FEG is designed with an automated set-up which eliminates the need to manually adjust parameters and allows for automated acquisition of high-quality images, thus freeing up more time for analysis. It offers a range of accessories for analysis such as integrated EDX, WDX, EBSD, and ASTAR. Furthermore, it can be upgraded with additional components such as the EDS automated alignment and the EBSD attachment. In addition, PHILIPS / FEI Quanta 250 FEG is compatible with FEI TomTom software, a powerful image processing and analysis package which provides multi-frame imaging, 3D tomography, Auto-Focus, and automatic particle/feature recognition. FEI Quanta 250 FEG is an exceptional piece of equipment for a vast range of SEM applications, with excellent analytical capabilities and outstanding flexibility. Its dual-segmented detector, automated set-up, and range of accessories make it an ideal choice for users seeking excellent performance, accuracy and dependability.
