Ricoh XW Series Eyepieces

Yes, the XW series is designed with a generous 20mm eye relief, which provides enough space to view the full field of view comfortably without needing to remove your glasses.

Lanthanum glass is a high-refraction, extra-low-dispersion material that helps minimize optical aberrations. This results in a sharper, more color-accurate image across the entire field of view.

Absolutely. The series features JIS Class 4 weatherproofing, meaning they are built to withstand splashing water and damp environments, making them reliable for extended outdoor stargazing sessions.

The barrel size you need depends on your telescope's focuser. Most standard telescopes accept 1.25-inch eyepieces, while larger or more advanced telescopes often support 2-inch barrels for a wider field of view.

The internal light-shielding technology is designed to reduce internal reflections and stray light. This significantly boosts contrast, allowing you to see finer details in planetary features or deep-sky objects that might otherwise be washed out.
