The BPC series binoculars are made by classical Porro prism design with central focusing. The central focusing knob is conveniently mounted under the middle finger and allows to rapidly bring the images in both eyepieces into sharp focus. For the people with different eyesight of the right and left eyes, provision is made for additional focusing of the right-hand eyepiece.
A rugged body made of light alloys protects against vibration and accidental shocks. No plastic materials are used in the binoculars – only the central focusing knob and the eyepieces in non-rubberized bodies are made of plastic. All the body joints and places of objective lenses and eyepieces attachments are filled with special sealing compound to obtain moisture- and dust-proof properties.
The binoculars perfectly operate under all climatic conditions at a temperature of –40 to +50oC.
All optical components have a multilayer antireflection coating, the prisms are made of high quality Bak4 optical glass allowing for an excellent image quality over the whole field of vision.
