The Stéréoloscope is a camera built with the format 45 x 107, which was adopted among a certain number of stereoscopic cameras essentially portable
It differs of its congenerics especially from the point of view of shape, volume and weight.
Its shape is that of a folding camera with two tensioners ensuring a perfect rigidity of the small plank lens-holder. It uses simple chassis receiving some plates of variable thickness; it is provided with glass ground for the focusing.
Its volume (6 x 3.5 x 13 centimeters.) and its weight (550 gr.) makes some most reduced and lightest of the camera of this kind.
We will mention for memory the main improvements which still  point at it for attention to the most demanding amateurs:
The off-centring of the lens (in the model with anastigmat)
The optional focusing either direct, or by means of a graduation up to 50 centimeters of the subject;
The ability to adjust the shutter for the pose or the instantaneous with variable speeds;
The change of aperture of the lenses for three distinct diaphragms;
The use of an automatic controller, preventing any error;
The tapping with the threading of the Congress for the adaptation with an ordinary foot,
etc, etc

As well, we will say only one word of manufacture to the point of view of finished execution; it is absolutely satisfying, and testifies of the care taken by the manufacturer to the raw materials implementation of choice by a staff, experienced by means of tools of a rare perfection.
