Equipped with a lens made of pure fluorite crystal, this unique compact spotting scope makes your travels impressive and unforgettable. The centerpiece of the TSN-550 Prominar spotting scope is undoubtedly the lens made of pure fluorite crystal. This naturally occurring mineral has the outstanding property of extremely low dispersion, which is not found in normal optical glass. By using this artificially cultivated crystal, it is possible to eliminate the phenomenon of chromatic aberration even into the non-visible range and drastically increase the resolution and contrast of the image. In the field of sports optics, Kowa is the only manufacturer in the world that uses this high-quality material in lenses. The exclusive use of fluorite crystals in top products is a testament to decades of optical development and an unwavering commitment to providing the best possible optics. With a length of only 27 cm and a weight of just 800 g, the TSN-550 Prominar is the perfect travel companion. The TSN-550 Prominar is not just a spotting scope; it also emphasizes the character of its owner as someone for whom only the best is good enough. Equipped with absolute top optics and high-quality mechanics, it is fully waterproof and nitrogen-filled. Equally compact and robust, it ensures outstanding imaging performance even in the toughest environments.
