Translated text:
' "Corolla" because corollary, in the sense that the eyepieces of this stereoscope have the same focal length as that of the shooting lenses (50 mm in general). The observed pair therefore restores the perspective observed in reality, to the extent that the distance between the lenses when shooting was equal to the distance between the eyes.

Advice:
- The eyepiece plate can be released by unscrewing the screw below the device by about 3mm. When reassembling, insert the plate parallel to the front face. Do not forget to screw it back underneath.

Focusing is normally done by the right knurled knob. Correction on each eyepiece is also possible by turning the black knurled knobs on the eyepieces. Do not lock by screwing back in. The interpupillary distance can be adjusted from 59 to 69 mm. Adjustment is done by manually moving the eyepieces apart or closer together, which move symmetrically.

The lighting requires two LR6 or AA batteries per lamp, their duration is approximately two hours.'
