Binocular military tool 3D model

Binocular fantasy. It is created not as a copy of any existing, though it can resemble some. Scale of the object is questionable, it's a bit more that usual. The diameter of front ocular is 20cm.All of the materials are procedural, the model is made in blender. Model uses plastic, metal, rubber and glass materials.Binocular is put in the box, the top of the box is emissioning light plane, the front wall of the box is empty to let in the sun light come.The circles are made of 128 vertices so it looks smooth, not square lensed (as a bunch of models if you zoom them in).
