[ED Glass Lenses for Sharp, High-Contrast Images] Compared to ordinary optical glass, ED (Extra-Low Dispersion) glass lenses have less change in refractive index across the wavelength range from blue to red. By suppressing chromatic aberration, natural images similar to those seen with the naked eye are obtained. [Bright and clear image with phase coating and dielectric multilayer coating] By applying a phase coating to the roof prism to correct phase differences and an ultra-high reflectivity dielectric multilayer coating to the auxiliary prism, light loss is suppressed and a bright and clear image is produced. This also contributes to improved resolution and contrast. [Fully Multi-Coated] By applying multi-coating (multilayer coating) to all lens and prism surfaces, high light transmission is achieved. 【Twist-Up Eyecups】Features a long eye relief design of 15mm or more. Reduces eye strain even during prolonged observation, and provides a wide field of view even for those who wear glasses. 【Waterproof Design】The waterproof design ensures peace of mind even in sudden rain outdoors or near water. Nitrogen gas is filled inside the body to prevent fogging of the lens. It conforms to JIS B7261 (ISO9022-8) for a depth equivalent to 1 meter (10 minutes) and has an IP rating of IPX7 (equivalent to 10 minutes).
