The origins of this third 'Focimeter' can be traced back to Thomas R Dallmeyer's '
Focometer' which was an optical test bench designed to ascertain lens focal
length and check the extent to which aberrations had been corrected. It is unclear

(a) If it is not possible, the absolute focal length of the combination is too long to
be measured by a focometer of this length. (6) If the image is smaller or larger
than the scale, then we can determine the absolute focal length. In this case we ...
