Multi-coated lensesAll air-to-glass surfaces are coated with multiple layers of anti-reflectivity coatings so that the maximum amount of light passes through the glass to the eyes and true colors can be revealed.
Phase Coated BaK4 PrismThe prisms inside the JUNGLE binoculars are made of high quality BaK-4 glass, phase coated, so that more light is reflected off their internal faces and passes through to the eye. Taken together, the fully multi-coated lenses and BaK-4 prisms maximize light transmission for the remarkably bright, highly detailed images.
