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-660 PROMINAR – a truly unique spotting scope, designed to make your journeys truly memorable and immersive.
PROMINAR – THE PINNACLE OF OPTICAL EXCELLENCE.
Only the finest optics deserve the accolade of the PROMINAR title. Optics that utilize Kowa’s unique benchmark feature – fluorite crystal, delivering simply the best optical performance available today.
At the heart of the TSN-660 PROMINAR series spotting scope beats a fluorite crystal objective lens. This natural mineral has an outstanding feature of very low dispersion that cannot be found in optical glass. This characteristic enables Kowa to eliminate color blur 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.
FLUORITE CRYSTAL – THE ULTIMATE VIEWING EXPERIENCE.
A mysterious stone called fluorite emits light like a firefly when it is heated or exposed to ultraviolet radiation. Fluorite has an outstanding feature of very low dispersion that cannot be found in optical glass, This characteristic enables Kowa to eliminate color blur almost completely and dramatically increase resolution and contrast. Fluorite is considerably more difficult to handle than optical glass, it requires highly advanced processing technology.
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 DIFFERENCE IS CLEAR.
The optimum optical material to minimize chromatic aberration is fluorite crystal.
Fluorite crystal with extremely low dispersion characteristics is used for the convex lens of the Kowa TSN-660 PROMINAR models.
MORE THAN JUST AN OPTIC – IT FITS YOUR WAY LIFE.
The TSN-660 PROMINAR 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-660 is the perfect travel companion.
A lightweight yet durable, fully waterproof and nitrogen filled chassis ensures performance in the toughest of environments.
