Online calculators and tools for spectroscopy and electron microscopy, free to use and share.
Calculators
UBC Nion Tools
Online calculators and analysis tools for the Nion U-HERMES 200, including EELS references and electron IMFP estimates.
Raman Tensors
Calculates symmetry compositions in polarization-resolved Raman scattering experiments.
STEM Ray Tracer
Interactive ray diagram of a dedicated STEM column — condenser, objective, projectors and EELS coupling, all as ideal thin lenses.
ARPES kz Calculator
Finds the exact photon energy at which photoelectrons have crystal momentum at the Brillouin zone center (Γ) or boundary. Photon momentum is included, so it is also valid for hard X-ray ARPES.
Vacuum Window Thickness
Sizes optical windows under a uniform pressure load, for vacuum chambers, cryostats and pressure cells. Round or rectangular, clamped or unclamped.
