The compact 8x25 Macroscope measures 3 5/8 inches by 2 1/4 inches by 1 3/4 inches and still delivers high-quality optical performance from a close-focus distance of 13 3/4 inches with its 8X magnification. The field of view at 1,000 yards is 342 feet. Despite its light weight (5.3 ounces), the Minox Macroscope is protected from wear and tear with tough rubber armor-coating, and it is waterproof to more than 16 feet. With a lens diameter of 25mm, an innovative optical system and multi-layer coating of the optics, the Macroscope ensures bright images with high contrast and accurate color rendition under all conditions. Minox also has considered those who wear eyeglasses, making the full field of view visible thanks to an extended exit pupil.
