Pentax PentaBright Technology: Your Best Solution for Top-quality Viewing
The complex science of optics requires attention to the type and quality of glass, design construction, eye relief, tube alignment, sealing against moisture, and user comfort. Pentax has been an innovator in the field of optics for over 90 years, so no one knows optics better. Pentax pioneered multi-layer lens coatings which greatly increase light transmission efficiency, thereby delivering bright, high contrast images without flare. This establishes the core of PentaBright technology.
All optical elements within every Pentax product are treated with their time-proven multi-layer coating, which not only improves light transmission to deliver bright, high contrast images without flare, but also reduces eye fatigue, even during extended observation.
Every Pentax Sport Optics instrument is built to the highest of standards using some of the toughest materials available. Pentax binoculars are encased in highly durable rubber-armored housings, which are designed to protect the optical mechanisms inside from shock and damage, while making them easier to hold. Pentax waterproof products are fully sealed and feature airtight construction. They are purged with laboratory grade nitrogen to provide a fog proof view in the harshest weather conditions and extreme temperatures.
The long eye relief offered in all Pentax Sport Optics allow 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.
Due to its outstanding refraction index, the BaK4 glass prism is highly acclaimed for its perfectly round exit pupil and clear, un-vignetted image.
Pentax aspherical optical elements greatly improve image brightness and sharpness, while minimizing disturbing distortions.
