[Features ED glass lenses for sharp, high-contrast images] These lenses utilise ED (Extra-low Dispersion) glass, which exhibits less variation in refractive index across the wavelength range from blue to red compared to standard optical glass. By minimising chromatic aberration, they produce natural images that appear just as they would to the naked eye. 【Bright and Clear Images with Phase Coating and Dielectric Multi-Layer Coating】A phase coating, which corrects phase differences, is applied to the Dach prism, whilst an ultra-high-reflectivity dielectric multi-layer coating is applied to the auxiliary prism. This minimises light loss to produce bright, clear images. It also contributes to improved resolution and contrast. [Full Multi-Coating] High light transmission is achieved by applying a multi-layer coating to all lens and prism surfaces. [Twist-Up Eyepiece] Designed with a long eye relief of 15 mm or more. This reduces eye strain during prolonged observation and provides a wide field of view even for spectacle wearers. [Waterproof Design] A waterproof design that offers peace of mind during sudden rain outdoors or when used near water. The interior is filled with nitrogen gas to prevent fogging inside the lenses. Complies with JIS B 7261 (ISO 9022-8) for submersion to a depth equivalent to 1 metre (for 10 minutes) and has an IP rating of IPX7 (equivalent to 10 minutes).
