Featuring premium optical components, a wide 70° field of a view, and generous 20mm eye relief for comfortable glassing, the SMC XW20 20mm Wide Angle Eyepiece is designed for use with Pentax65mm, 80mm and 100mm spotting scopes. This 20mm focal length eyepiece yields 32x magnification with the PF-100ED, 27x with the PF-80EDA, 26x with the PF-80ED, and 19.5x with the PF-65EDA II and PF-65ED II. Extra-low dispersion lanthanum glass elements provide a balanced image with minimal aberrations, while fully multi-coated air-to-glass surfaces and partially coated laminated surfaces avoid reflection for optimal light transmission. A light-shielding diaphragm further reduces internal reflections for a bright, high-contrast image.

 

The eyepiece is constructed to Japanese Industrial Standard Class 4 for water resistance. It is not to be used underwater, but will easily withstand light rain or dew. Its diameter is the American standard of 1.25", so it can be used in other spotting scopes or telescopes, and it offers a 43mm adapter mounting thread under the removable eyecup.
