Description
This early Cuff-style solar microscope was designed by Peter Dollond. The square plate can be fixed to a window shutter with two screws. The instrument has a large, rectangular mirror which can be controlled by two wing nuts; one connected to a pinion for angle variation and the other to control the rotation. The body-tube attached to the brass plate and can be screwed in to secure it. A condensing lens is also attached to the body-tube and on the other side is a spring-barrel tube which holds the final condenser — which comes in the form of dovetail slides — the specimen and the projection lens. The instrument comes with six projection lens which are engraved 1 to 6. The focusing is by rack work controlled by the small thumbscrew located at the side of the spring-barrel. The instrument comes with a fitted mahogany case which holds all the components in fitted compartments. The case is secured by two brass swing hooks and also has a lock with a functional key.
The microscope comes with the following accessories: 6 projection lens, 3 dovetail-slide lens, 3 bone slides and 1 talc box.
