Product introduction
● Main features
1. Bright and natural look
ED glass is used for the objective lens to correct chromatic aberration that causes color bleeding. 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 over the entire visible light range, and bright, natural color tones and a clear field of view can be obtained. In addition, a bright field of view has been achieved by applying a multilayer coating to all lenses and prisms.
2. Large aperture and high magnification
Since the objective diameter is as large as 56 mm, it can be observed with sufficient brightness even in dimly lit conditions. The "20x56" is a high-magnification model in the "MONARCH" series. Even if the observation target is far away, it can be captured with a dynamic field of view.
3. Excellent waterproof performance
By filling the inside of the main body with nitrogen gas, it has a waterproof structure that does not easily cause fogging or mold inside the optical system. Since it is safe against sudden rain and splashes, it can be used for a wide range of purposes such as nature observation, astronomical observation, and bird watching.
4. Pursuing ease of use
Since the turn slide (rotational extension) method with click is adopted for the eyepiece, the eyepiece can be fitted to the face at a position where it is easy to look into. In addition, because the eye relief * is long, it is possible to obtain a wide field of view even while wearing glasses. A flip-down objective lens cap is used to prevent loss.
* The distance from the eye position to the eyepiece where the entire field of view can be seen without vignetting when looking through the binoculars.
