I use 2 Zeiss special wide achromats with a focal length of 100mm. Max diameter is 42.5mm. With Zeiss T* coating. Magnification is 3x. You can see the whole 6x7cm picture. The lenses are large enough diameter that eyeglass wearers can see the full field without vignetting. A 3D dream.

Wood for the viewer body, metal for the lens mounts.
For king size slides 6x7cm, or panorama, 31x69mm, 24x69mm.
