اپتیک های الکترونی میکروسکوپ الکترونی روبشی SEM مدل Apreo
|
High-resolution field emission SEM column with:
– High-stability Schottky field emission gun to provide stable high-resolution analytical currents
– Compound final lens: a combined electrostatic, field-free magnetic and immersion magnetic objective lens*
– 60° objective lens geometry: allows tilting larger samples
Automated heated apertures to ensure cleanliness and touch free aperture changes
Through-the-lens differential pumping for low vacuum* reduces beam skirting for the most accurate analysis and highest resolution
Beam deceleration with stage bias from -4000 V to +600 V
Continuous beam current control and optimized aperture angle
Double stage scanning deflection
Easy gun installation and maintenance – auto bake-out, auto start, no mechanical alignments
Guaranteed minimal source lifetime: 12 months
