Product Description

70º apparent field of view, 20mm eye relief, weatherproof housing, multilayer coated extra low dispersion lanthanum glass

Clear, Comfortable Viewing Thanks to 70° Apparent Angle 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 which is comfortable to view especially for glass wearers.

High-Grade Optics for Exceptional Image Quality

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.

PENTAX-Original Multi-Layer Coating for Outstanding Light Transmission Efficiency

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.

Advanced Light-Shielding Technology for Improved Image Contrast

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.

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 dew.
* The XW-series eyepieces are not designed for underwater use and should not be submerged under water.

Inserts into your telescope 1.25" (31.7mm) eyepiece barrel easily. When the rotatable eyecup is removed, it also offers an adapter-mounting screw/thread (43mm in diameter with a 0.75mm pitch).
