"LEED" is a device manufactured by OCI that can perform low-speed electron diffraction measurements. The electron gun of this product has a diameter of 10mm, providing a wide field of view on the screen, and minimizes the shadow area caused by the electron gun, allowing for the acquisition of LEED pattern images. Additionally, by using a cylindrical structure for the lens part, the outgassing within the electron gun is efficiently discharged through the side slits. Various options such as Auger electron spectroscopy measurement functionality, MCP attachment, linear drive mechanism, shutter, and image acquisition device can be selected according to measurement purposes. [Features] - Electron gun with a diameter of 10mm and a wide field of view on the screen - Use of μ-metal in a cylindrical shape to prevent magnetic field interference - Digital controlled power supply can provide the necessary voltage and current for the LEED device through digital control - Compatible flange types include ICF203, ICF152, and ICF114 *For more details, please refer to the PDF materials or feel free to contact us.
