New Fully-multi-coated optics
Fully multi-coated lenses serve the essential purpose of maximising
the amount of light passing through a lens, thereby prevent flare and ghosting from interfering with your view. 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.
Due 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.
Aspherical lens elements
edge-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.
Inner Focus Optics Design
this sophisticated optical design is critical to low-maintenance and long life guarantee. exposure to airbourne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the housing and disrupt functionality.
Helicoid three-stop eyepiece rings that permit fine adjustment for maximum viewing comfort
Exterior rubber coating that provides the binoculars with superb resistance to shocks and impacts.
