Rotary-Viewer-3.jpg (198335 bytes) ROTARY STEREOSCOPE - While the exterior is an elegant walnut design that can blend nicely with room  furniture, the guts of the instrument are made of precision designed and machined mechanical structure made of aluminum and other quality mechanical components.
Rotary-Viewer-4.jpg (203339 bytes) ROTARY STEREOSCOPE - Precision is the key to this instrument. Slide mounts are kept tightly in exact position in their channel slots, but don't require special tools for replacement. To the right of the slides, another channel holds note-cards visible through the note-window of the case.
Quimby.jpg (154062 bytes) QUIMBY - This limited edition of high quality stereoscopes was produced in a limited edition of 50 units in 1996. It was reviewed in Stereo World magazine.

As its superior "brother" the Quimby above, it is made of acrylic with glass lenses. Designed and produced at Levy Design Studios in Portland, Oregon USA.
Quimby-Junior-with-Adapter.jpg (140315 bytes) QUIMBY JUNIOR - With adaptor.  Multiple cards can be displayed in flip-pockets for use in exhibitions and judging of card entries. Cascade Stereoscopic Club in Portland, Oregon, uses 10 of these practical viewers in its exhibitions. Large number of visitors can sit at tables and view stereocards in a relaxed and convenient fashion.
Colapsable-Holmes-Viewer.jpg (103680 bytes) COLLAPSIBLE VIEWER  - This viewer is made of 3 pieces that can be dismantled in seconds with two thumb-screws allowing for flat storage or transport. Plastic lenses cover a standard Holmes size card. Designed and produced at Levy Design Studios in Portland, Oregon.

Slide-Mounter.jpg (146991 bytes) SLIDE MOUNTER - This is a precision device for accurate mounting of stereo transparencies in RBT mounts while viewing in real-time the results with achromatic lenses. Accurate positioning of the chips is achieved through the use of micrometer screws. Used also as a viewer for medium size stereo slides by changing the lenses. 
Slide-Mounter-2.jpg (145771 bytes) SLIDE MOUNTER - Access to the slides and mounts is done easily by lifting both the lens holder and micrometer device. Designed and produced at Levy Design Studios in Portland, Oregon.
 Slide-Stereotrope.jpg (187924 bytes) SLIDE STEREOTROPE  - The name is a combination of Stereoscope and Zoetrope and so is the function of this apparatus in which 24 stereo slides of a stop-motion sequence allow a viewer to see a very short 3D movie. The person looks through a stereoscope featuring achromatic lenses and spins a handle to rotate the wheel housing the slides. Designed and produced at Levy Design Studios in Portland, Oregon.
 Slide-Stereotrope-1.jpg (228592 bytes) SLIDE STEREOTROPE - A view from the back shows a stroboscope with a synchronizing sensor and precisely placed dots behind each slide. As a dot moves in front of the sensor, it triggers the strobe producing a very short flash "freezing" that pair of images in our eyes. Just as in the movies, the fast presentation of still images in sequence produces the sensation of motion - and in this case it's not only moving, but also in 3D.
 Card-Stereotrope.jpg (410376 bytes) CARD STEREOTROPE -  Just as in an old Nickelodeon parlor, turning the handle of this apparatus, shows a sequence of 60 images in succession creating the sensation of a moving scene. The difference of course is that this sequence features 60 stereocards and the person viewing it can see a short 3D movie. The viewing  stereoscope uses the same kind of custom made glass lenses as used in the Quimby stereoscope above. Designed and produced at Levy Design Studios in Portland, Oregon USA.
