Passion HD 10x50

All glass that is finely polished will, at a micro level, have grooves and channels on its surface. Hydrophobic coatings applied with nano-application technology will fill these micro-grooves and channels, making a smoother surface that is easier to clean and that will not hold water, dirt, oil, and debris. Based on a nanoscale application technology, the GPO PASSIONdrop hydrophobic coatings are designed and applied to the exterior surfaces of our optical products to repel water, dust, oil, and dirt. Products that use this modern technology are proven to have dramatic improvements in smudge repellency, stay cleaner longer, and are easier to clean when necessary.

GPObright is a proprietary coating process that maximizes light transmission through each surface of an optical element. As light hits an optical surface, normal uncoated high-performance glass can reflect up to 5% of that light, redirecting this light so it does not transmit through the optical system. However, when these high-performance lenses are vacuum-coated with GPObright lens coatings, up to 99.7% of the available light passes through each optical surface. Furthermore, when every surface of the entire optical system is properly coated, total light transmission can reach up to more than 92%, making the optical image of a GPO binocular or riflescope “bright,” even in the lowest light conditions.
