Pentax SMC XW 10mm 1.25" eyepiece

Pentax Eyepieces: Precision Optics for High-Grade Spotting Scopes

XW-Series

Enjoy crystal-clear, comfortable viewing with the Pentax XW-Series eyepieces. Boasting an extra-wide 70-degree apparent angle of view and an extended 20mm eye relief, they offer an immersive, wide-perspective image that enhances your observing experience.

High-Grade Optics for Exceptional Image Quality

Our XW-Series optics are engineered with high-refraction, extra-low-dispersion lanthanum glass elements, ensuring a finely balanced image with minimal aberrations. Designed to combat the disruptive blackout effect, they effectively compensate for pupil spherical aberration, delivering sharp, clear views.

Pentax-Original Multi-Layer Coating for Superior Light Transmission Efficiency

Featuring Pentax's proprietary multi-layer coating, these eyepieces optimize light transmission efficiency. Air-contacting lens surfaces benefit from the original multi-layer coating, while laminated surfaces receive an innovative partial coating, ensuring transmission rates surpassing 90% across the visible light spectrum.

Advanced Light-Shielding Technology for Enhanced Image Contrast

Harnessing Pentax's advanced computer simulation technology, the XW-Series incorporates a strategically positioned light-shielding diaphragm, minimizing internal reflections for brighter, higher-contrast images.

A Range of Magnifications for Varied Applications

Choose from four different magnifications (7mm, 10mm, 14mm, and 20mm) to suit your specific observing needs, catering to both casual and specialized applications.

Weatherproof Construction for All-Weather Viewing

With JIS Class 4 weatherproof construction, the XW-Series is built to withstand challenging conditions, allowing you to observe even in drizzle or nighttime dew. Note: These eyepieces are not designed for underwater use.
