TL;DR: It is proposed that small spherical viruses close to 300A in diameter, such as the picornaviruses or phages, make good specimens for testing the performance of an electron microscope in cryo-mode.

TL;DR: In this paper, a geometrical construction is given for determining the position of the image formed by a spherical mirror, which is used to develop algebraic expressions for the longitudinal spherical aberration and the sine condition error, enabling rapid calculations to be made.
