PENTAX
Pentax Corporation is pleased to announce the introduction of the SMC PENTAX XW Series of eyepieces designed for use with Pentax-brand spotting scopes and telescopes in ground and astronomical observations. Consisting of eight models with a focal length ranging from 3.5 mm to 40 mm, the new XW series features a wide apparent angle of view ( 70 degrees), JIS Class 4 weather-proof construction and a long eye relief ( 20 mm ). The new optics, incorporating high-refraction, low-dispersion lanthanum glass elements and PENTAX-original multi - layer coating , delivers bright, high-resolution images with minimal aberrations and distortions.
The new XW series retains all the popular features of the current XL series, including eyepiece shape , while upgrading many vital specifications. All XW models feature a 70-degree apparent angle of view, delivering a more dramatic , wide-perspective image than the 65 degrees of the XL-series. Laminted optical elements are threadet with the innovative partial coating, which offers mugh higher light transmission capability than conventional full-surface coating. Thanks to advanced computer simulation technology , internal reflections are drastically reduced to produce brighter , clearer images.
Replacing the excisting XL-series , the new XW-series can be used with the PENTAX PF-80ED, PF-EDA and PF-100ED spotting scopes and a range of PENTAX telescopes to optimize their performance and capability. The XW 7, XW 10, XW 14 and XW 20 models are suited for both ground and astronomical applications, while the XW3.5, XW5, XW30 and XW40 modells are exclusivly designed for astronomical observations.
About the new Pentax XO , new Orthoscopic series not much info is available, excapt that they have a standart 1.25" barrel , a slightly larger FOV and new better multicoatings.
