Pentax SMC XW14 14mm Wide Angle Eyepiece (1.25")

Featuring premium optical components, a wide 70° field of a view, and generous 20mm eye relief for comfortable glassing, the SMC XW14 14mm Wide Angle Eyepiece is designed for use with Pentax65mm, 80mm, and 100mm spotting scopes. This eyepiece yields 44x magnification with the PF-100ED, 37x with the PF-80EDA, 36x with the PF-80ED, and 28x 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 can't 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 optics that accept eyepieces, and it offers a 43mm adapter mounting thread under the removable eyecup.
