    Product description

    The Kowa Spotting Scope TSN-99S Prominar is the new flagship of Kowa. The TSN-99S is equipped with a large 99mm pure fluorite crystal objective lens, which in combination with a Kowa XD lens delivers superior performance in low light. This special combination, combined with the improved optical coatings, virtually eliminates chromatic aberration, even at high magnifications. Because the TSN-99S is equipped with a dual focus mechanism, the image can be focused faster and more accurately in just a few smooth revolutions, just with an index finger. The fine focus mechanism provides the final control to view the image razor sharp.

    Because the Kowa TSN-99S uses a 100% magnesium alloy, it is a compact and lightweight spotting scope in its class. The TSN-99S is easy to carry and has a fully waterproof and nitrogen sealed housing with Kowa KR coating on the optics. This makes the binoculars reliably robust.

    Chromatic aberration occurs due to the diffusion of light and the different wavelengths of light that concentrate at different positions, which can result in a red or purple border around the subject. The optimal optical material to minimize chromatic aberration is Fluorite Crystal. For the convex lens of the TSN-99A/99S, a Fluorite Crystal with extremely low dispersion characteristics is used. Instead of an ordinary optical glass lens, the hollow lens in combination with the Fluorite Crystal lens is made of glass with special dispersive properties to further reduce chromatic aberration. This combination virtually eliminates chromatic aberration and redefines the standards for color brilliance.

    Fluorite crystal is only used in the top models of Kowa.

    Key features Kowa TSN-99S Prominar:

    • Large 99mm fluorite crystal lens
    • The fluorite used as an optical lens is an artificially grown monocrystal with "ultra-low dispersion", a property that ordinary optical glass does not have. It is an ideal lens material that almost completely eliminates chromatic aberration (colour blurring). The fluorite crystal produced by the advanced processing technology Kowa has built up over the years guarantees the ultimate viewing experience.
    • Dual focus mechanism (Quick and fine focusing)
      The fast focus, with a large and easy-to-turn knob, will focus in two revolutions from infinity to five meters. The fine focus, with smooth movements and great precision, is extremely useful at high magnifications and for digiscoping.
    • Eyepiece lock mechanism
      The eyepiece bayonet mount now has an attractive feature. An eyepiece locking mechanism has been added to the holder to prevent the eyepiece from being lost or unexpectedly falling out.
    • Strong, lightweight and portable
      Thanks to a 100% magnesium alloy body, the TSN-99 Prominar series is one of the most compact and lightweight spotting scopes of its size. A fully waterproof and nitrogen-sealed housing plus Kowa KR coating on the optics makes the spotting scope reliably robust.
      Another great advantage of magnesium alloy is that there is no turbulence in the body. The light rays pass straight through the body and the image is incredibly quiet.
    • Designed for digiscoping
    • 100% compatible with the KOWA SYSTEM. Easily change eyepieces, accessories and use digiscoping adapters for DSLR cameras and smartphones. Create a truly flexible optical instrument for many applications.
    • 10-year warranty
