The GeminiSEM 300 can be operated in different modes:
- High Vacuum (HV) mode – standard mode, for analyzing conductive specimens
- Variable Presurre (VP) mode – for analyzing non-conductive, strongly gassing or moist specimens without any need for special specimen preparation
- Nano VP mode – enhanced VP mode with an inserted Beamsleeve aperture below the objective lens
Equipped with: standard Everhart-Thornley secondary-electron (SE) detector; Gemini II column with Inlens and EsB (Energy selective BSE) detectors; insertable 4 quadrant backscattered electron (BSE) detector; Oxford Inst. EDX detector
Operated since 2018.
