1.15mm large wide-angle eyepiece with blue-coated lenses provides a broad viewing field. The design uses a modular system, and performance is easier to interpret in low light, though very dark scenes may still appear dim. 30mm large objective lens with flat-thread interface and a 60mm main objective lens to boost brightness. Matte spray on the inner wall helps prevent light scattering inside the objective cone and reduces stray light. Dust-proof grease helps absorb dust and maintain lens cleanliness. Optical lenses with green film coating use multi-layer coating across the full optical path to deliver a more comfortable viewing experience, sharper imaging, a wider transparent band and a flatter vision field, improved eye protection, and better color accuracy. Zoom adjustment allows 10x to 30x magnification for flexible viewing from wide scenes to detailed close-ups. Use scenarios - Birdwatching and wildlife observation from a distance in parks or forests, where bright, clear resolution and a wide field of view help identify details. - Scenic viewing or landscape exploration, enabling distant features to be observed with enhanced brightness and sharpness. - Outdoor events or activities such as sports, travel, or sightseeing, where quick transitions between wide and close-up views improve detail recognition.
