This object consists of a pair of green, molded, plastic pieces with round lenses set in them. These lenses and their surrounds can be adjusted along a metal bar to widen or narrow the space between them. This metal bar has a scale on it. On each side of the plastic pieces, thick metal wires extend perpendicularly in a rectangular shape. These pieces can be folded flat against the lens surrounds. These metal pieces act as a stand to allow the lenses to be set above a stereoscopic photograph.
Folded, the spectroscope fits into a rectangular leather case.
Primary Materials: Plastic, Glass, Metal
On the front of the plastic lens surrounds: “893”
Dimensions (cm): With case: 19.7cm x 9.5cm x 1.5cm
This a portable stereoscope. It enables a viewer looking at a stereoscopic photograph to see the images as a single, 3D image.
Good. The plastic has some small signs of wear, particularly where the metal stands meet the plastic surrounds. Paint on the metal bar between the lenses is worn in places.
