MIRA3 LM
Outstanding optical properties,
flicker-free digital image
with super clarity.
A fully PC controlled FE SEM intended for both – for high vacuum as well as for low vacuum operations. Outstanding optical properties, flicker-free digital image with super clarity. Sophisticated user-friendly software for microscope control and image capturing using Windows™ platform, standard formats of stored images, enhanced image archiving, processing and measurements, automatic set up of the microscope and many other automated operations are characteristic features of the equipment.
Analytical Potential
- LM MIRA chamber provides superior specimen handling using a full 5-axis motorized compucentric stage and ideal geometry for EDX and EBSD.
- Numerous interface ports with optimized analytical geometry for EDX, WDX and EBSD as well as for attaching many other detectors
- First-class YAG scintillator-based detectors
- Selection of optional detectors and accessories
- Full operating vacuum can be obtained quickly and easily with powerful turbomolecular and dry fore vacuum pumps, electron gun pumping with an ion pump
- Investigation of non-conductive samples in variable pressure mode versions, excellent results in the investigation of magnetic samples
- Several options for chamber suspension type ensure effective reduction of ambient vibrations in the laboratory.
MIRA3 Configurations
MIRA3 LMH
This large-chamber model with an extended motorized manipulator operates at high vacuum for the investigation of conductive samples with extraordinary imaging quality.
MIRA3 LMU
This variable-pressure FE SEM supplements all the advantages of the high vacuum model with extended facilities for low vacuum operation, enabling the investigation of non-conductive specimens in their natural uncoated state.
Microscope Control
All microscope functions are controlled by keyboard, mouse and trackball via the program MiraTC using Windows™ platform.
