◆Tripod adapter (TRA-3) included/[MONA520X56] MONA 520 By applying a phase difference correction coating to the auxiliary prism that uses a highly reflective dielectric multilayer film and the roof prism, the transmittance is improved in the entire visible light range, providing bright, natural color tones and clear visibility. In addition, the multilayer coating applied to all lenses and prisms provides a bright field of view.
◆Excellent waterproof performance By filling the inside of the main unit with nitrogen gas, it has a waterproof structure that prevents fogging and mold from forming inside the optical system. It can be used for a wide range of purposes, such as nature observation, astronomical observation, and bird watching, as it is safe from sudden rain and water splashes.
◆Pursuing ease of use The eyepiece uses a turn-slide (rotation) method with a click, allowing you to fit the eyepiece to your face in a position that makes it easy to see. In addition, the long eye relief* allows you to get a wide field of vision even while wearing glasses. In addition, a flip-down objective lens cap is used to prevent loss. ■Specifications ■Magnification (x): 20 Objective lens Effective diameter (mm): 56 Actual field of view (°): 3.3 Apparent field of view (°): 59.6 (65.6) Field of view at 1000m (m): 58 Pupil diameter (mm) : 2.8 Brightness : 7.8 Eye relief (mm) : 16.4 Minimum focusing distance (m) : 5.0 Mass (weight) (g) : 1235 Height (mm) : 199 Width (mm) : 146 Interpupillary width adjustment range ( mm): 60~72 Accessories: Eyepiece cap x 1, objective cap x 2, soft case x 1, strap x 1, tripod adapter TRA-3 x 1□
