| Author | Wenham |
| Contribution | Introduced a binocular microscope. |
| Reference | Bradbury |
| Notes | He used a prism to split the light beam and deflect half of it up a second tube that converged on the main tube. Popular, but useful only for low magnification (because of loss of transmitted light). After about a decade, the design was superseded by better designs. [An example, made by Fisher of London, is in the collection of W. C. Campbell.] |
