  • XW 3.5mm, 5mm, 7mm, 10mm, 14mm, 20mm eyepieces may be used with our PF series Spotting Scopes (except PF 63 Zoom)
  • Full multi-coated lenses increase light transmission and contrast
  • High refraction, extra-low dispersion lanthanum glass elements deliver bright, high resolution images with minimal distortions and aberrations

  • Weatherproof construction for greater durability
  • Long eye relief for comfortable viewing with or without glasses

With unsurpassed optical clarity and a short focal length, the XW 5.0 offers a 70 degree field of view for easier viewing. All of our eyepieces are constructed with a high-refraction, low-dispersion lanthanum glass that consistently delivers bright, high-resolution images with minimal distortion. In addition, all XW series eyepieces are built to JIS Class 4 weather-proof standards which increases their durability in less than ideal conditions. Designed for use with a wide range of telescopes and PENTAX brand spotting scopes, the XW series eyepieces are a clear choice for ground and astronomical applications.


Compatible with the following: PF-65 and PF-65 ED II series spotting scopes, PF-80 series spotting scopes, PF-100 series spotting scopes
