Product Description


Kowa TSN 553 Straight Spotting Scope

New from Kowa, the TSN-550 PROMINAR series spotting scopes re-define the level of performance available from a compact travel scope. The range comprises of two models, the TSN-553 (angled) and the TSN-554 (straight) which  weigh just 810g and 800g respectively. They are extremely compact too, at just 27cm in length. The TSN-550 series are the first compact travel scopes with 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 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. The scopes are fitted with a bespoke 15-45x zoom eyepiece and will focus down to 3m.
