Kowa's definition of 'crystal clear' makes sense with their Prominar technology
Sponsored Feature

“Crystal clear, literally..."
Crystal clear - a phrase you will often hear loosely used in the world of sporting optics, but take a look through a Kowa PROMINAR TSN-880 or PROMINAR TSN-550 spotting scope and that’s exactly what you will get, both physically and visually.
How does this happen?
Put simply - a solid piece of pure fluorite crystal is crafted into a perfectly polished and multi-coated lens to deliver the true definition of what is crystal clear, giving you the ultimate viewing experience while birding.
Japan's Kowa are currently the only spotting scope manufacturer to use artificially produced pure fluorite crystal in the manufacture of their optical lenses. Some manufacturers have in the past used fluorite in their scopes but have found it too expensive and too problematic to continue in full-scale production. They instead use ED glass in their compact spotting scopes – This is a cheaper raw material that is much easier to work.
At best, there are higher grades of ED glass, some containing a diluted mix of fluorite to attain the features of fluorite - but this still performs on a lower level than fluorite in its purest form.
Fluorite crystal delivers the best viewing experience available today, eliminating virtually all chromatic aberration and delivering images of outstanding resolution and contrast. If anybody has the right to describe their optics as crystal clear - it’s Kowa.
