(LBVO)

• Intended for stereoscopic viewing of the operation field with magnification 2.5x and 3.5x and illumination of it by "cold" light.
• OVC-1 illuminator with fibre-optic conduit can serve as a light source creating high illumination by "cold" light (OVC-1 light source is supplied separately).
