Pentax SMC XW 5mm 1.25" eyepiece

Pentax Eyepieces: Enhanced Viewing Experience for High-Grade Spotting Scopes

XW-Series

Enjoy clear and comfortable viewing with the Pentax XW-Series eyepieces. Boasting an expansive 70-degree apparent angle of view and an extended 20mm eye relief, these eyepieces offer an exhilarating, wide-perspective image.

High-Grade Optics for Exceptional Image Quality

The XW-Series optics feature high-refraction, extra-low-dispersion lanthanum glass elements, crafting a finely balanced image with minimal aberrations. Specifically engineered to mitigate the bothersome blackout effect, they effectively counteract spherical aberration of the pupil, ensuring sharp, clear views.

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

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

Advanced Light-Shielding Technology for Enhanced Image Contrast

Utilizing Pentax's advanced computer simulation technology, the XW-Series features a strategically positioned light-shielding diaphragm, significantly reducing internal reflections for brighter, higher-contrast images.

A Choice of Four Magnifications to Meet Specific Applications

Select from four different magnifications (5mm, 7mm, 10mm, and 14mm) to suit your specific observing needs, catering to both casual and specialized applications.

Weatherproof Construction for All-Weather Viewing

Built with JIS Class 4 weatherproof construction, the XW-Series is designed to withstand various conditions, allowing for observation even in drizzle or under nighttime dew. Note: These eyepieces are not intended for underwater use.
