Hitachi S-4500 (Field Emission Scanning Electron Microscope)

The S-4500 is a cold field emission SEM with advanced high resolution imaging at low voltage operation (capable of <1 kV), digital image processing, versatile sample chamber and stage design, and thoroughly computer controlled electronics.

The S-4500 has a new objective lens and secondary electron detector design which provides excellent imaging resolution, particularly in low voltage operation. The S-4500 has a built-in recursive frame memory which enhances signal to noise ratio and permits crystal clear images on CRT monitors at flicker-free TV-scan rates. This facilitates field selection, focusing, and astigmatism correction. The frame memory of the S-4500 is expansive. It has two(2) 1,024 x 1,024 and one(1) 512 x 512 pixel memories. The 1,024 x 1,024 pixel images may be transferred to magneto-optical disc or a SUN IPC workstation in a digital format using the Voyager system.

The S-4500 is computer controlled throughout. It is possible to control the S-4500 and read out the operating conditions through an external workstation via RS-232C interface. The S-4500 is currently interfaced with a SUN IPC running Noran's Voyager, digital image and x-ray spectra acquisition system. Specifications:

• 1.5 nm resolution
• 0.5 - 30 kV accelerating voltage
• 3 stage electromagnetic lens
• 2 secondary electron detectors
• 1 backscattered electron detector
• x-y-z translation, -5° to + 45° tilt, 360° rotation (continuous) 50 mm diameter specimen size Sun IPC running Noran's Voyager, digital image and x-ray spectra acquisition system.
