Zeiss
The Zeiss Sigma HDVP is a scanning electron microscope (SEM) designed for high-resolution imaging. The Zeiss Sigma HDVP offers acceleration voltage from 0.02 kV to 30 kV and a magnification range of 10x to 1,000,000x. The Zeiss Sigma HDVP's specimen chamber measures 358 mm, and the system includes multiple detectors such as HD AsB, CL, STEM, and SCD.[1]

The Sigma HDVP has an acceleration voltage range from 0.02 kV to 30 kV and a magnification range from 10x to 1,000,000x. The specimen chamber measures 358 mm in diameter.[1][3]
The specimen stage provides five axes of movement: X 30 mm, Y 130 mm, Z 50 mm, tilt from -3° to 70°, and rotation 360°. Detectors include an HD AsB detector, a CL detector, a STEM detector, and an SCD. Pumps comprise a turbomolecular pump, an ion getter pump, and an ultimate high vacuum pump. The system is controlled by a PC with Windows 7, 4 GB RAM, a hard disk drive, and a 19-inch TFT monitor.[1]
The Sigma HDVP uses a field emission electron gun to generate a focused electron beam that is scanned across the sample surface. The primary beam interacts with the sample, producing secondary electrons, backscattered electrons, and other signals, which are collected by detectors to form an image. The variable pressure mode allows imaging of non-conductive samples by introducing a gas into the chamber to reduce charging effects.
