The Pentax A series binoculars consist of roof and porro prism that provides not only fine field of view but also waterproofing during harsh weather. The AD 9x32 WP Binoculars has a wide angle of view with 9X magnification and 32mm objectives that contains new fully multi-coated optics to lessen the outside reflection and new enhanced light transmission coatings to add up the access of light. Having a BaK4 prism, and new enhanced light transmission coating, Pentax AD’s can provide crystal clear images and superb contrast. Its fully waterproof and nitrogen-purged (JIS Class 6) body is built with rubber cover to prevent dust and water penetration. This series has eye-relief and close-focus features thanks to its twist-up eyecups that provide inner focusing. Pentax A series binoculars are also tripod mountable.
Product Features in Detail
New Fully-multi-coated optics
Fully multi-coated lenses serve the essential purpose of maximizing 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.
New Enhanced Light Transmission Coatings
PENTAX binoculars take quality optics to the next level by applying a new, optimized film-deposition technology on lens and prism surfaces resulting in increased light transmission which creates bright images with accurate color rendition
BaK4 prisms
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.
Phase Correction
The complex optical design of roof prism binoculars provide durable, compact, yet lightweight design but require a higher level of optical perfection. A phase-correction coating is applied in the full range of roof prism binoculars to maximize image viewing quality.
PENTAX Waterproofing
PENTAX waterproof products are fully sealed and purged with laboratory grade nitrogen to provide a fog proof view in the harshest weather conditions. With a JIS Class 6 rating, PENTAX waterproof binoculars can even be submerged in up to 3 feet of water.
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.
Nitrogen purged
Nitrogen is a chemical element and a colorless, odorless and tasteless gas. It contains very little humidity and is therefore used to “purge” binoculars and spotting scopes of the high humidity air that is part of our environment. Due to the low humidity factor, nitrogen prevents condensation from forming on the internal lenses of optical instruments during phases of rapid temperature change. Furthermore, because nitrogen is purged into the optical instrument at slightly above atmospheric pressure, dust and other miniscule particles are prevented from entering the housing.
Long eye relief design
The long eye relief offered in all PENTAX Sport Optics allows the viewer to see the entire field of view clearly and effortlessly. This is especially beneficial to eyeglass wearers, and allows viewing for extended periods of time without added eye strain.
Other Features
Exterior rubber coating that provides the binoculars with superb resistance to shocks and impacts.
