PENTAX applies multiple layers of coatings to every surface of every element and prism in the full Sport Optics line-up. These fully-multi-coated optics assure the maximum light transmission resulting in a clear, crisp view of the world.\n\nBaK4 prisms\nDue to its outstanding refractive index, the BaK4 glass prism found in all PENTAX sport Optics is highly acclaimed for its perfectly round exit pupil and clear, unvignetted image.\n\nAspherical lens elements\nEdge-to-edge sharpness is a vital element to comfortable viewing. To achieve this, we utilise aspherical lens elements in our eyepieces. This is a specially shaped lens design that reduces aberration to a minimum.
