Crafted by Edmund Hartnack about 1885, this device is a replacement for the eyepiece in a microscope. The microspectroscope was photographed and described by Gerard Turner in his excellent volume Collecting Microscopes.

This device is a direct-vision spectroscope that has been adapted for use with an optical microscope. The slit is adjusted by a knurled brass knob after a sample has been placed in the glass tube to the right of the eyepiece. Inside the eyepiece is a prism, which is translated with a rack and pinion mechanism. Accessories include a wooden storage box that is covered in black cloth and lined with purple velvet and silk.
