Pentax Eyepieces

We at PENTAX believe that the eyepiece is crucial to the overall optical performance of spotting scopes. That is why our eyepieces are engineered to the exacting standards originally required by the astronomy community. Furthermore, that is why we made the 1.25inch (31.7mm) connector our standard. We are among an elite few who use rare materials like Lanthanum glass to optimise light transmission for unsurpassed clarity and brightness. Successfully, it seems, since astronomers and ornithologists agree that PENTAX eyepieces are among the best available world-wide.
