3D Prism Stereo Viewer, Wheatstone - with 60 Deg FOV! Museum Quality

Description

For sale is a custom designed 3D Prism for SUPER WIDE FOV (Field of View).
I had this prism designed by USA's best visual optical Engineer, Bruce Walker.   Bruce is a renown author of many visual optics books used in Universities and one of the best visual optical designers in the USA.   I spent many years designing and building all kinds of 3D viewers.  I worked with Bruce on nearly all my designs.  We also had the benefits of using a CodeV optical design lab for final check.    I also have listed, two other working prototype viewers.
Included in this sale is the working prototype which you see in the pictures and all the design documents required to manufacture more of this prism.   This prism would be ideal in a museum environment whereas if they like the prototype, they can order more units as the design document package is "bid ready".    It will be sent in pdf file to the successful bidder.  No one else has a copy of these design documents.   The optical design documents include all information necessary to price quote and build the optics.
The premise of this 3D Optical viewer is to view two stereo images placed away from the person as the diagram illustrates.  The original inventor of this premise was Sir Charles Wheatsone in 1838, hence the name in the title.   The difference was, Wheatstone used mirrors, whereas this is a prism, a massive one, weighing 10 lbs!   This prism is made from the BEST quality Schott Glass.  The benefit of the prism over a mirror in this application, it produces a much wider FOV for that WOW factor.  This prism will allow up to 60 deg FOV!   This is equivalent to the experience of sitting a few rows back in a standard cinema theater.  (not IMAX screen)
This prism can be used in many applications, its limited by your imagination.  The sale includes a face plate with a pair of achromatic doublet lenses as you see in the pix.  The fl is 357mm to view images about 14" from the eye.   This was one of the original concepts of the blue viewer shown in the pictures above.   It can see a 14" square at 14" view distance, or about 12" from the prism.  (some of the ray distance is used while being folded inside the prism)
What images can be viewed?  Anything!
One application would be a fixed display housing a stereo pair of back lit transparencies.  One of the benefits of back lit transparencies, is they hold an incredible amount of resolution vs. digital displays and with proper back lighting, they have tremendous tonal range.   This assumes, the original content was recorded in sufficient detail and it was successfully relayed to the transparency.   This can be used as a multi image viewer, as you can change out the transparencies, but this would be cumbersome.   Hence why its an incredible, ONE LOOK, and WOW application for museums, trade shows, hotel lobbies, etc.   It would have to be built on a pedestal to lower and raise for each persons height.  A counter weight would be ideal to make it feel weightless.  The new owner would be responsible for making the prism work in their application.
Another application is digital displays for the imagery.  This would make the ideal multi image viewing application.  Of course you need the computer expertise so displays l/r images display simultaneously, or 3d video.
If the image plane gets far enough away from the prism, you do not need optics.  How far depends on the age of the people viewing... with people under 30, its simple to view at any distance 14"+ with no viewing optics required.   Less than 48" viewing distance and people over 45 would benefit by using a pair optics designed specifically for your view distance.  I am including a second pair of achromat doublet lenses that have a fl of 687mm, which allows viewing a 30" square, at approx 27".   The also fit in the face plate.  These were the two distances I was experimenting with, hence these fl's.   Seen in pix above with face plate...the lenses are interchangeable with retaining rings included.
The cost to design a prism like this in the K - 10K range with the optics.  The cost to build the first prism was K.   If a museum liked the concept, they can reproduce these prisms in the 0 - 0 price range, based on volume and where they are manufactured.
What u are buying is a prism ready to use for experimentation and / or reproduction.  Build your own application.
Packed very well in a "box in a box" method, using a 200lb test outer box.  It is packed well enough for international travel.
