Specifications

The German Precision Optics PASSION HD 8.5x50mm Schmidt-Pechan Prism Binocular is built with a Schmidt-Pechan prism system and utilizes BAK-4 prism material, which are foundational for delivering bright, high-resolution images. The 8.5x magnification combined with a generous 50mm objective lens diameter results in a substantial 5.88mm exit pupil, a critical factor for low-light performance and maintaining a bright view even as ambient light diminishes. This wide exit pupil is significantly larger than what you’d find on smaller objective lenses, making it ideal for twilight observation. The GPObright optical coating applied to every glass surface is a proprietary technology designed to enhance light transmission and color fidelity, further contributing to the binocular’s superior viewing characteristics.

Further enhancing its utility, the binocular features double HD glass technology, which helps reduce chromatic aberration for crisper images. The field of view is 315 ft at 1000 yds, offering a good balance between magnification and situational awareness, allowing you to scan larger areas without constant head movement. Eye relief is a comfortable 0.77 inches, accommodating users who wear glasses. The center focus system ensures quick and precise focusing, with a close focus distance of 3 meters, enabling detailed observation of nearby subjects. Weather resistance is rated as waterproof with a 500m water resistant mark, and it’s also fogproof, making it suitable for diverse environmental conditions.

Performance & Functionality

In practice, the German Precision Optics PASSION HD 8.5x50mm Schmidt-Pechan Prism Binocular excels at its primary function: providing a clear, bright, and detailed view.
