The GPO Passion HD 8.5x50mm Binoculars - Model B640 from German Precision Optics stand as the pinnacle of optical excellence. As the flagship products of GPO, these binoculars are crafted to the highest optical standards, offering exceptional low-light optical advantages. Users can capture remarkably fine details from extended distances while relishing in superb color contrast images. This exceptional visual quality is made possible through GPO's exclusive GPObright lens coating technology.
The PASSION HD binoculars feature an expansive field of view, immersing users in the scenes they observe, making them feel an integral part of the spectacle. Remarkably lightweight and compact, these binoculars provide a nearly imperceptible presence around the user's neck.

GPObright Technology:
GPObright is a proprietary coating process that maximizes light transmission through each surface of an optical element. When light strikes an optical surface, normal uncoated high-performance glass can reflect up to 5% of that light, redirecting it away from the optical system. However, when high-performance lenses are vacuum-coated with GPObright lens coatings, up to 99.7% of the available light passes through each optical surface. When every surface of the entire optical system is correctly coated, total light transmission can reach more than 92%, ensuring a "bright" optical image even in the lowest light conditions.
Double HD Lens:
A Double HD lens is the result of chemically laminating multiple extra-low dispersion lenses to create a single, multilayer, high-performance optical lens. This process minimizes light reflection on the surface of multiple lenses, resulting in enhanced resolution, improved color contrast images, and reduced chromatic aberrations. This benefit is evident in all GPO products supporting this feature. While this process is commonplace in the photographic market and among premium photographic lens manufacturers, it has now transitioned into premium sporting optics.
