Utilizing Kowa's PROMINAR Fluorite Crystals lenses, the new compact Kowa TSN-550 PROMINAR is truly a unique spotting scope, designed to make your journeys truly memorable and immersive. This PROMINAR 55mm series sets a new benchmark standard in the compact spotting scope market
A TRUE MILESTONE A journey of over 60 years of heritage, refining and developing techniques passed down decade to decade from the Kowa optical masters in Japan. This legacy leads us to where we are now – introducing the new compact Kowa TSN-550 PROMINAR – a truly unique spotting scope, designed to make your journeys truly memorable and immersive.
Not only does the TSN-550 PROMINAR adopt the unique styling of it’s larger predecessor, it also inherits what makes the TSN-880 still unrivalled to this day – decades of Kowa optical development. The result? A new benchmark optic in the compact spotting scope market.
PROMINAR – THE PINNACLE OF OPTICAL EXCELLENCE. Only the finest optics deserve the accolade of the PROMINAR title. Optics that utilise Kowa’s unique benchmark feature – fluorite crystal, delivering simply the best optical performance available today.
Fluorite Crystal Lenses Fluorite crystal makes for the ideal lens material with "ultra-low dispersion" properties not possessed by an ordinary optical glass. This outstanding specification adds the featured benefit of a near-completely reduced chromatic aberration, or color blur, to provide users with the ultimate viewing experience.
Kowa's KR Coating Kowa's KR coating protects the lenses from dirt and other foreign residues that may affix to the lenses during normal use. Fingerprints or oil can easily be removed with the proper lens cleaning techniques.
Waterproof and Fogproof The housing is waterproof to JIS Protection Class 7 and filled with dry nitrogen gas to prevent internal fogging to ensure image clarity.
Dual Focus Mechanism Kowa's well-developed focus system has progressed to a dual focus system with smooth movement at high magnifications for pinpoint accuracy in image display. The quick focus can easily shift from infinity to 5m in two revolutions with the large and manoeuvrable knob. The fine focus moves fluidly to create pinpoint accuracy and is extremely useful at high magnifications and with digiscoping systems.
Tripod Mounting Screw A tripod mounting screw allows the scope to be safely secured to both 1/4 and 3/8 inch mount tripods.
Twist-Up Eyecup Twist-up multi-step eyecup allow customization for easy viewing even when wearing eyeglasses.
