Bring distant subjects into closer view with Alpen Optics 10x50 ED Waterproof Binoculars. The 10x magnification supports detailed observation across open landscapes, while the 50 mm objective lenses provide a large optical surface for gathering available light. ED glass helps reduce unwanted color fringing so fine details and natural colors remain easier to distinguish.
ED Glass and PXA Phase Coating
The optical system combines extra-low dispersion glass with BaK4 prisms and PXA phase coating. ED glass helps maintain cleaner color separation around high-contrast subjects. PXA phase coating supports improved contrast and image detail through the prism system, making the binoculars well suited to wildlife observation, birding, scenic viewing, and other outdoor activities where clear detail matters.
Comfortable Long Eye Relief
Long eye relief provides additional viewing distance between the eyepiece and the eye. This helps create a more comfortable viewing position during longer observation sessions and can be especially useful for users who prefer additional space at the eyepieces.
Waterproof Outdoor Construction
Waterproof construction helps the binoculars handle changing outdoor conditions. Combined with 10x viewing power, 50 mm objectives, ED optics, BaK4 prisms, and PXA coating, the design provides a focused feature set for observing distant wildlife, landscapes, and other outdoor subjects.
