| This is a Smith & Beck Educational Microscope, described in The Achromatic Microscope by Richard Beck, 1865. Beck described this as a "third-class instrument" that would be useful for someone who does not need a binocular microscope. The microscope body is mounted on a compass joint allowing it to be oriented vertically or horizontally. Coarse focus is acomplished by sliding the body in the mounting tube. Beck called this "quick motion focus". Fine focus ("slow motion focus") is accomplished via the milled screw head at the top of the support pillar. This moves the body support arm against the support tube. The original configuration placed the screw head at the bottom of the pillar. The mirror is mounted to a tube that descends from the stage. It has two reflecting surfaces: plane and parabolic. The microscope is mounted to a mahogany board, on which is also mounted the optics holder frame. Included are two eyepieces, three objectives, and the substage aperture. The microscope has a small condensing bullseye lens for epi-illumination of opaque samples.
There is an additional mahogany frame that holds the accessories: two Nicol prisms, darkfield condenser, livebox, and Lieberkuhn. The entire system can be folded and packed into a mahogany case. Microscope is 28cm high. The case 12.5cm x 14cm x 30.5cm. Microscope featured 9/2024 |
