Descriptions
These binoculars use a roof-prism design with phase correction. The magnification is 8? and the objective lens diameter is 56 mm. The optical system is made from BaK-4 glass. The lens coatings include dielectric coating, fully multi-layer anti-reflective coatings, green finish, plus phase coatings on the prisms. The eye relief is about 19.67 mm, making them eyeglass-compatible. The twilight factor is approximately 23.66, and their relative brightness is 49. The field of view is about 6.51 degrees, which corresponds to about 114 meters at 1,000 meters distance. The closest focusing distance is 3.5 meters. They have a diopter adjustment range of ?4 diopters and an interpupillary distance of 60?72 mm. Focusing is done centrally, and the eyecups are twist-up. The body is made from metal and polycarbonate, filled with argon gas, and is water-resistant. They can operate in temperatures from ?20 ?C to +50 ?C and can be mounted on a standard ?-inch tripod thread.
