Microscope performance is limited by environmental factors, not just aberrations. Understanding and controlling room disturbances is crucial for achieving high-resolution imaging and spectroscopy.

Area of Science:

  • Microscopy
  • Instrument Science

Background:

  • Aberration correctors enhance resolution but do not address environmental instabilities.
  • Increasing spatial resolution in microscopy amplifies sensitivity to environmental disturbances.

Purpose of the Study:

  • To highlight the critical role of the microscope's surrounding environment in performance.
  • To introduce methods for quantifying environmental impacts on advanced microscopes.

Main Methods:

  • Characterizing instrument response to magnetic, mechanical, acoustical, and thermal disturbances.
  • Predicting environmental limits on imaging and spectroscopy performance.

Main Results:

  • Environmental factors like computer fans and chillers can limit microscope performance.
