How to acquire kits
In order to divulge the use of the stereoscopic images in this site as an aid to the visualization of three dimensional mathematical objects, Atractor has tried to obtain acrylic prisms at a moderate cost.
The kits can be acquired directly at Atractor at the price of 15,25 euros (VAT included).It is obvious that at this price the objects in question do not have a Professional optical finish, but that is not necessary for the use for which they are destined.
The complete kit with stand, prisms and separator can be acquired directly at Atractor, in Porto. It can also be sent by mail. In this case consult Atractor first by email to know if there are available kits at the time before sending a check for the value of the kit (+postage).
