The PICO-RHEED set consists of a "Low Emission type RHEED" and a "Micro Channel Plate (MCP) screen," which reduces the damage to a sample from the E-beam. Yet, the diffraction image on the fluorescent screen is bright and clear.
This would be useful for those who study and analyze the growth of organic
thin films.
Features
• Less damage to the sample (1/500 to 1/2800)*.
• MCP (Micro Channel Plate) Screen Included
• RoHS-compliant
• Interlock
• Port for Differential Pumping (optional)
• Compatible with kSA400 RHEED Analysis System * Data acquired at AVC, CO., LTD.
