Abstract
A sliding binocular body has two optical assemblies which slide on an intermediate plate to adjust for intraocular distance and which slide closed. Two shells are joined to form one assembly. Front and back contour plates cover the assembly. A field and eye lens holder slides into the box through the back plate. An eye piece is attached to the lens holder. Inward horizontal surfaces have inward extending rails, which engage outward facing grooves on the intermediate plate. The two shells are secured together and joined to the intermediate plate before mirrors are slid and clamped into place. The objective lenses are placed in position, and the contour plates are sealed in place. The eye lens and field lens are inserted in the holders before the holders are inserted in the assemblies. The assemblies hold and clamp mirrors against fixed reference surfaces. Objective lens holders formed in the assemblies permit vertical or horizontal adjustment of an objective lens before its fixing. The intermediate plate has vertical projections on opposite ends which fit into recesses in the inward surfaces of the assemblies to limit outward travel and to hold the assemblies in closed position.
