Abstract
Significance Biological electron cryomicroscopy is limited by the radiation sensitivity of the samples and the consequent need to minimize exposure to the beam. This, in turn, results in low-contrast images with a poor signal-to-noise ratio. The current practice to improve phase contrast by defocusing results in contrast transfer functions necessitating image restoration to provide interpretable data. Phase plates enable in-focus phase contrast, but the existing ones, including the thin film Zernike-type phase plate, suffer from severe limitations, such as a short usable life span, fringing artifacts, and problems in using them in automated data acquisition procedures. The Volta phase plate presented here solves those problems and has the potential to become a practical solution for in-focus phase contrast in transmission electron microscopy.
