The XW 20 eyepiece is designed for use with a wide range of PENTAX spotting scopes and telescopes. Ideal for both ground and astronomical observations, this eyepiece features fully multi-coated lenses to increase light transmission and color quality, high-refraction lanthanum glass elements for high-resolution images with minimal aberrations, and JIS Class 4 weatherproof construction for durability. Engineered using advanced computer simulation design technology, this high-performance eyepiece provides a 70 degree field of view and 20mm eye relief.

All smc PENTAX XW-series eyepieces feature an extra-wide 70-degree apparent angle of view and an extra-long 20mm eye relief to deliver an exciting, wide-perspective image.The high-performance XW-series optics incorporates high-refraction, extra-low-dispersion lanthanum glass elements to produce a well-balanced image with minimal aberrations. It is particularly designed to reduce the disturbing blackout effect by effectively compensating the spherical aberration of the pupil.All lens surfaces that come in contact with air are treated with the original multi-layer coating, while all laminated surfaces are treated with the innovative partial coating, to offer the light transmission efficiency of more than 90 percent (an astonishing 96 percent at 550nm) over the visible light spectrum.Thanks to PENTAX's advanced computer simulation technology, the XW series features a light-shielding diaphragm at the most effective position to drastically reduce internal reflections for a brighter, higher-contrast image.With four different magnifications (7mm, 10mm, 14mm and 20mm) to choose from, the XW series accommodates a wide range of both casual and specialized applications.The XW series features JIS Class 4 weatherproof construction, making it possible to use it in drizzle or under night dew. The XW-series eyepieces are not designed for underwater use and should not be submerged under water.The XW series features the American-standard 31.7mm for smooth, easy installation on the PENTAX spotting scopes. When the rotatable eyecup is removed, it also offers an adapter-mounting screw/thread (43mm in diameter with a 0.75mm pitch).

Designed for high-quality, high-precision outdoor viewing. The PENTAX PF-65EDA incorporates porro-prism optics and a 65mm objective lens with PENTAX-exclusive ED (Extra-low Dispersion) optical elements to deliver sharp, high-contrast images with minimal chromatic aberration. With a 45-degree slanted lens barrel, the PF-65EDA offers hours of comfortable, fatigue-free viewing. This spotting scope also feature a compact, lightweight body with nitrogen-filled waterproof construction (JIS Class 6), a collet-type eyepiece receptacle for an American-standard 31.7mm (1.25 inch) sleeve, a protective rubber housing, and accessible reach by either hand. When mounted on a tripod, the lens barrel can be twisted 90 degrees clockwise or counterclockwise from thedefault position at top or 180 degrees from side to side along with easy-to-locate pointers at top and 45-degree angles, to assure the best viewing position. The extendible rubber lens hood comes with a sight line to facilitate target-line adjustment. To optimize the performance of these new spotting scopes, PENTAX has developed three compact, high-performance XF-series eyepieces, all featuring a bright, high-contrast image, an American-standard 31.7mm sleeve and focal lengths ideal for outdoor viewing and bird watching. The smc PENTAX XF8.5 and XF12 are standard unifocal eyepieces, offering a focal length of 8.5mm and 12mm, and a magnification of 46 and 32.5 times, respectively,

Housed in a lightweight magnesium-alloy body, the PF-100ED spotting scope features the time-proven porro-prism optics and an extra-large 100mm objective lens incorporating ED (Extra-low Dispersion) glass elements to produce a sharp, clear image with minimal chromatic aberration. Its straight-line optical barrel design makes it easy for you to locate the subject. The scope barrel has an American-standard 31.7mm-diameter eyepiece receptacle, which accepts one of six optional eyepieces of different magnifications to satisfy many different viewing requirements. This receptacle also has a dust-shielding glass to make the scope barrel airtight and waterproof (rated JIS Class 6). Coupled with a nitrogen-injected barrel, this unique mechanism prevents the internal fogging caused by sudden temperature changes.Because of its superb image quality, interchangeable eyepieces and airtight body construction, the Pentax PF-100ED Spotting Scope can be used for a wide range of subjects and performs flawlessly even under demanding conditions in the field. Pentax offers six optional interchangeable eyepieces for the PF-100ED Spotting Scope to meet individual requirements: five fixed-focus XL-type models with magnifications of 22.5, 30, 45, 60 and 90 times, and one zoom model offering a magnification range of 26 to 78 times. All these eyepieces are commonly used for astronomical telescopes and renowned for their outstanding image reproduction.
