The Pentax SP 20x60's are a pair of high-quality, waterproof, nitrogen-filled binoculars suited to long-range or astronomy observations. The large 60mm objective lenses are housed inside a rugged, rubber armoured body and also come with the newly developed coatings to maximise light transmission and ensure a bright, clear viewing experience.
Pentax SP 20x60 WP Observation Binoculars:
- New fully multi-coated optics
- Phase correction
- Protective lens coating
- Nitrogen purged
- Unique hydrophobic coating
- Aspherical lens elements
- Magnesium alloy construction
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.
Protective Lens Coating:
All optical surfaces are delicate and must be handled with care to prevent scratching. To add to the durability of the Z- and S-series Water Proof binoculars, Pentax has added a protective, Nano technology coating that helps deflect water, oil, dust and dirt. This allows Pentax binoculars to withstand the harshest viewing conditions.
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.
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 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.
Unique Hydrophobic Coating:
Water droplets on a lens have a negative influence on the ability of light to enter the objective lens. By using a unique water repellent coating on all outer lenses we make water drops "bead" into small, deformed droplets. The deformed droplets cause less distortion and "slide" more easily off the lens. Your binocular remains fully functional even in rain, snow, fog or condensing breath.
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.
Nitrogen is a chemical element and a colourless, odourless 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.
Superb impact resistance:
The body is made from magnesium, which adds toughness while keeping the binoculars light. In addition, the exterior rubber coating provides the binoculars with superb resistance to shocks and impacts.
Helicoid three-stop eyepiece rings that permit fine adjustment for maximum viewing comfort.
