The TwinScope is a unique stereoscope for viewing stereographs or other side-by-side 3D prints (with combined maximum width of 8 inches). In designing the product, the aim was to replicate the viewing experience of the classic Holmes stereoscope, but in a museum-worthy hanging stereoscope for viewing stereographs that are not only hand-held, but also matted and framed, in exhibition cases, or otherwise displayed. Like the Holmes stereoscope, the TwinScope has a lens hood–in this case rubber, and large enough for eyeglass wearers–as well as prismatic lenses to give a clear, magnified view. A hanger incorporated into the wooden lens boards allows the TwinScope to hang on the wall or mount onto a pedestal. Focus is achieved by looking through the TwinScope and adjusting ones distance to the stereograph from 6-8 inches away. Additionally, when the TwinScope is turned upside-down, the hanger becomes a handle for hand-held viewing of loose stereographs (the handle will be lengthened thanks to feedback from a PSSCC member), offering a robust alternative to using fragile historic viewers.
TwinScopes were first used in an exhibition produced on the history of the stereograph for the Onondaga Historical Association earlier this year (http://colleenwoolpert.com/Sight-Unseen) and have been purchased locally by the University of Washington Special Collections, the Henry Art Gallery, the Bainbridge Island Historical Museum…and by one PSSCC member at the December club meeting!
