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-554 PROMINAR – a truly unique spotting scope, designed to make your journeys truly memorable and immersive. 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.

At the heart of the TSN-554 Prominar Spotting Scope beats a fluorite crystal objective lens. This natural mineral has an outstanding feature of very low dispersion that cannot be found in standard optical glass. This characteristic enables Kowa to eliminate colour blur (chromatic aberration) almost completely and dramatically increase resolution and contrast. Fluorite crystal is a unique feature of Kowa spotting scopes and is a testament to decades of Kowa optical developments. Kowa put forth extra care, time and technique to produce the ultimate viewing experience with a pure fluorite crystal lens. It’s what makes Kowa unique.

The optimum optical material to minimise chromatic aberration is fluorite crystal. Fluorite crystal with extremely low dispersion characteristics is used for the convex lens of the Kowa TSN-554 Prominar Spotting Scope model. This scope has a generous eye relief of 16.5 mm to 16.0 mm.

Measuring just a mere 270 mm in length and weighing only 800 grams, the TSN-554 PROMINAR is truly compact and makes the perfect travel companion. Kowa’s dream was to create an ultra-portable spotting scope delivering the highest levels of optical performance. The TSN-554 Prominar Compact Spotting Scope represents a way of thinking, a way of life. An optic that enhances every moment you use it. It’s unique. A spotting scope this compact creates new opportunities. Wherever your journey takes you, the Kowa TSN-554 is the perfect travel companion. This Kowa Spotting Scope is designed in Japan.

A lightweight yet durable, fully waterproof and nitrogen filled chassis ensures performance in the toughest of environments. Not only does the TSN-554 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.
