The Binocular Microscope

摘要

AMONG microscopists there are some who regard the binocular merely as a toy or plaything, while others take it more seriously and consider it an instrument useful in scientific research. The bulk of microscopes in use are, however, monoculars. This no doubt is partly due to the less cost and greater portability of the monocular instrument, and partly to the failure of the Wenham and Stephenson binoculars with high-power objectives, which of course means that if high-power work had to be done, one could not get on with a binocular alone, a monocular would have to be added to the outfit; the purchase of two microscopes instead of only a monocular would necessarily deter many from even thinking of buying such "a useless plaything as a binocular."
