Robert Hooke's Compound Microscope (replica)
From the accompanying card:
There are no surviving examples of Hooke's original microscopes. However his constructions are well documented, including in his seminal book Micrographia, published in 1665. A reproduction microscope is shown here. In the early use of this type, illumination of the specimen was from above. Later developments included the use of a mirror to provide trans-illumination.
