    • Compound and simple microscope (Inv. 2664, 3217)

This instrument, built by Andrew Pritchard, can be used as either a compound microscope or a simple microscope. A pillar set on a tripod holds a tilting limb carrying the mirror, converging lens, body-tube and stage. The image is focused by rackwork, inserted in the tilting limb that supports the body-tube. The eyepiece is Huygenian. The arm supporting the body-tube carries a collar in which a lens can be inserted when the instrument is used as simple microscope. There are objectives, a micrometer, and accessories for handling specimens.
