Description

70° viewing angle, 20mm eye relief, plus weatherproof housing for various applications, clear, comfortable viewing through 70° shining viewing angle and 20mm eye relief. All smc Pentax XW series eyepieces feature an extra-wide 70 degree angle and an extra long 20mm eye relief for an exciting, wide perspective. Picture. Premium Optics for Exceptional Image Quality: XW Series high performance optics feature high-refraction lanthanum glass elements, extra low dispersion to produce a balanced image with minimal aberrations. It is specially designed to reduce the annoying darkening effect by effectively balancing the spherical aberration of the pupil. Pentax original multi-layer coating for excellent light transmission efficiency. All lens surfaces that come into contact with air are treated with the original multi-layer coating, while all laminated surfaces are treated with the innovative partial coating to provide the light transmission of more than 90 percent (astonishing 96 percent at 550 nm) over the visible light spectrum. Advanced light shielding technology for improved image contrast Thanks to PENTAXs advanced computer simulation technology, the XW Series features a light-shielding membrane at the most effective position to dramatically reduce internal reflections for a brighter, high-contrast image. A selection of six magnifications for specific applications with four different magnifications (3rd 5mm, 5mm, 7mm, 10mm, 14mm and 20mm) to choose from, the XW series offers a wide range of both casual and specialized applications. Weatherproof construction for all weather viewing. The XW series features JIS Class 4 weatherproof construction, making it possible to use it in drizzle or under night dews. * XW Series eyepieces are not designed for underwater use and should not be submerged under water. Standard eyepiece sleeve and integrated adapter mounting screw. The XW series features the American Standard 1. 25 inch hose (31st 7mm) for smooth, easy installation on any telescope and/or Pentax spotting scope. When the rotating eyecup is removed, it also offers an optional adapter mounting screw/thread (43 mm diameter with a 0. 75mm Pitch
