Built With the Advanced Microscopy Community.
Waviks works with scientists and engineers at Oak Ridge National Laboratory, the Center for Nanophase Materials Sciences, Sandia National Laboratories, the University of Tennessee, Knoxville, and NC State University. Before founding Waviks, the team installed and supported more than 900 port-mounted nanomanipulators and gas injection systems at Omniprobe. Vesta development was supported by NSF SBIR awards 1721719 and 1853201.
FAQ
Common Questions Before a Compatibility Review
Will Vesta fit my microscope?
Vesta has configurations for Tabletop SEM (SEC Alpha), full-size SEM/FIB, S/TEM, and custom vacuum systems. We review ports, chamber geometry, and working distance before quoting.
Do I need to build my own laser setup?
No. Vesta is a complete laser system that mounts on a port of your microscope. Aether control software is included.
What laser options are there?
Vesta supports pulsed and continuous-wave lasers, with wavelengths from 200 to 2,000 nm depending on the source and optics. Heating, EEGS, and optical-excitation systems include an onboard pulser that can drive compatible CW lasers with pulse widths as short as 50 ns. See Products for laser-output power and focused-spot specifications.
How hot can Vesta heat a sample?
There's no maximum beyond what your sample tolerates. Published TEM work on an Ag-Ni thin film reached ~1445 °C in simulation DOI: 10.1017/S1431927618015465
What do you need from me for a review?
Microscope make and model, available ports, sample type, the measurement you want, and any laser-safety requirements.
