Main Features of PENTAX ZD ED Series.
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.
Enhanced Light Transmission
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.
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.
ED-Objective lenses
To build superior binoculars the ultimate challenge is to avoid colour errors (Chromatic aberration). Several techniques are available but by far the best results can be achieved by using ED (extra low-dispersion) glass in the objective lens. ED-lenses have a high breaking index with minimal dispersion. The result is comparable to the use of Apochromatic lenses; but now only 2 lens elements are used. The advantage of this technology is clear; the binocular is lighter in weight and more compact.
Hybrid Aspherical lens element
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. Hybrid-Aspherical lens elements have the additional advantage of superior functionality while being lightweight and compact.
Dielectric coating
Dielectric Coating of the prisms serves to enhance the colors of the image. Multiple layers of surface correction coatings are “vaporized” onto the surface of the prisms in a vacuum. This maximizes the quality of visible light in the color spectrum between infra-red and ultra-violet as it passes through the glass.
Enhanced Light Transmission.
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.
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.
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.
Inner Focus Optics Design
This sophisticated optical design is critical to low-maintenance and long life. Exposure to airbourne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the housing and disrupt functionality.
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.
