Pentax SMC XW 23mm Eyepiece for Spotting Scopes and Astronomical Telescopes (2-Inch)
The Ricoh Pentax XW 23mm Eyepiece is a high-performance, wide-angle eyepiece for use with high-grade spotting scopes.
Clear, Comfortable Viewing Assured by an 85-Degree Apparent Angle of View and 20mm Eye Relief
With an 85-degree apparent angle of view eyepiece, the XW 23 is newly added to the SMC Pentax XW-series lineup featuring an extra-long 20mm eye relief to deliver an exciting wide-perspective image.
High-Grade Optics for Exceptional Image Quality
The high-performance XW 23 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 for 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 a light transmission efficiency of more than 90 percent (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 23 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 23mm eyepiece features JIS Class 4 weatherproof construction, making it possible to use it in drizzle or under night dew. This eyepiece is not designed for underwater use and should not be submerged underwater.
Sleeve Size and Eyecup Design
The XW 23 eyepiece provides a 50.8mm installment diameter. When you remove the screw-on eyecup. it also provides a screw thread with a 43mm diameter and a 0.75 pitch.
Comprehensive Lineup to Accommodate All Applications
Featuring functional, practical focal lengths, the XW eyepieces series provides a comprehensive lineup that accommodates all types of applications, from low-magnification viewing of stars to high-magnification observation of planets.
