Redesigned to feature individual units that easily snap together to create a dual unit, or can be used individually as hand-held slide holders. This is the perfect instrument for training with strabismics, non-strabismics or with pursuit and jump ductions at true distances.
For in-office presentation of tranaglyph series, Polaroid Vectograms, 550 OPB Free Space Fusion Opaque B Card, and 550 TRB Free Space Fusion Transparent B Slide.
