KOWA TSN-550

PURE FLUORITE CRYSTAL SERIES

PURE FLUORITE CRYSTAL.

At the heart of the TSN-550 PROMINAR series spotting scope beats a pure fluorite crystal objective lens. Fluorite crystal 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 is considerably more difficult to handle than optical glass, it requires highly advanced processing technology.

Fluorite crystal is a unique feature of Kowa spotting scopes and is a testament to decades of Kowa optical developments.

Not only is the pure fluorite TSN-550 PROMINAR ultra compact,
but it delivers incredible resolution.
