Unknown Optical Instrument

This object consists of a metal tube with a eyepiece-type knurled end at one end, and a broader cylindrical piece at the other. At the broader end, a smaller metal tube-shaped piece is attached. This is adjustable and ends in a piece with a cylindrical hole through it, with a [Read More...]

This is a brass lens or eyepiece. The tube of this lens is quite narrow, with flared ends, one of which is much broader than the other. At the smaller end there is a small pinhole opening. At the wider end, there is a threaded attachment and a convex lens.

This object has a solid rectangular metal base. Mounted horizontally on top of this on a chunky curved metal support is a cylindrical microscope tube (both the tube and the support are parts of a repurposed microscope). Added to one end of the tube there is an additional cylindrical piece [Read More...]
