Le Min­imus is a com­pact man­u­al mul­ti-view stere­o­scope that holds 24 glass slides. Turn­ing the knobs on the sides moves the front pan­el out­ward, allow­ing a slide to drop into posi­tion before the lens­es. Fur­ther rota­tion trans­fers the viewed slide to a stor­age com­part­ment below, and the next slide moves into place. Once all slides have been viewed, invert­ing the device resets them to their orig­i­nal posi­tion. The slides can be stored in remov­able box­es that can be placed on top of the view­er so that the views can slide into the box, allow­ing for quick and effi­cient slide replace­ment. A 45x107mm ver­sion was also available.
