At the heart of the TSN-550 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 colour 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. Measuring just a mere 270mm in length and weighing only 800g, the TSN-550 PROMINAR is truly compact and makes the perfect travel companion.
