Pentax SMC XF12 12mm Wide Angle Eyepiece lanthanum glass (1.25")


Good clean used condition.

Featuring premium optical components, a wide 60° field of a view, and generous 18mm eye relief for comfortable glassing, the compact SMC XF 12mm Wide Angle Eyepiece is designed for use with Pentax 65mm, 80mm, and 100mm spotting scopes. This 12mm fixed focal length eyepiece yields 52x magnification with the PF-100ED, 43x with the PF-80EDA, 42x with the PF-80ED, and 32.5x 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 scopes or telescope focusers, and it offers a 30.5mm adapter mounting thread under the removable eyecup.
