Detector LVSTD

Detectors offered include the original Low Vacuum Secondary Tescan Detector - LVSTD

• True secondary electron imaging under low vacuum conditions
• Perfect displaying the fine surface topography
• Good-quality investigation of non-conductive and water-containing materials without special preparation
• Fine imaging of the surface structure of materials with low atomic number
• Compact design of the LVSTD allowing a fast and easy interfacing to any chamber manufactured by TESCAN
