Title

Smith, Beck & Beck Student Microscope

Description

The early Wenham binocular compound microscope was sold to a Mr. W. Bean on the 31st May 1856 according to the records. The instrument is signed "Smith, Beck & Beck, 31 Cornhill, London 1088." on the body-tube. The microscope stands on a reversed Y-shaped base connected to the lower pillar which ends in brass trunnions which allows for inclination. The instrument includes a plano-concave mirror in a gimbal on an articulated arm connected to a sliding collar. The mechanical stage has an attachment which allows the specimen to be held in place by balancing it on a shelf, and the upper level of the stage can also be rotated to adjust. The stage can be adjusted along the X and Y axis via rack work controlled by the two thumbscrews located at the side of the stage. Beneath the stage is an iris diaphragm with 3 apertures that can be rotated. Coarse focusing is achieved by rack and pinion mechanism controlled by the two large thumbscrews at either side of the body-tubes. Fine focusing is controlled by the labelled thumbscrew located behind the stage. At the top of the binocular body-tube is the inter-ocular adjustment via rack work.

The microscope comes with the following accessories: 2 low power ocular lenses, 2 medium power ocular lenses, 2 high power ocular lenses, 2 objectives with signed brass canisters: "1/5 in Smith, Beck & Beck, 31 Cornhill, London" & "2/3 in Smith, Beck & Beck, 31 Cornhill, London." A Lieberkuhn and cover, a sub-stage dark well holder and set of 3 dark wells, 1 sub-stage polarizer, 1 eyepiece analyzer, 1 lucida, 1 Zoophyte trough, 1 erector lens, 1 high power monocular body tube, 1 selenite slide, 1 micrometer slide, 1 bulls-eye condenser with stand (missing the steel rod.)
