Variable pressure microscope with large chamber and 5 axes motorized stage
VEGA\\LSU is a fully PC controlled scanning electron microscope designed for high as well as low vacuum operating.
Strengths:
- possibility of examination of non-conducting, water containing specimens in their natural state at low vacuum conditions in microscope chamber
- quick and easy achievement of clean working vacuum by means of turbomolecular and rotary pumps, easy and fast switch from high vacuum to low vacuum working mode
- innovative and powerful electron optics with four lenses
- a great variety of working modes
- fast and clean turbomolecular-pumped vacuum system - no water cooling required!
- a comprehensive suite of sophisticated, intuitive sotfware for microscope control, image archiving, measurements, processing and analysis
- network operations, remote control and diagnostics
- 11 chamber interface ports and a comprehensive choice of detectors and accessories
- optimized analytical geometry allowing simultaneous EDX, WDX and EBSD
- accurate and reliable automated analyses utilizing fast and precise computer-controlled stage motorization, including motorized compucentric tilt.
- remote control of the microscope including stage movements control and possibility of remote diagnostics
- wide choice of supplementary accessories
