Kowa TSN 883 Angled Spotting Scope Special Offer Kit

The pure fluorite crystal used in these models is the optimum optical material for reducing chromatic aberration, providing the ultimate viewing experience. (TSN-883/884 only.) 

The extraordinary light gathering capability supports observation during dusk and during dawn. 

  • "PROMINAR" Lens 

    One of the major causes of deterioration of viewing quality in optics is chromatic aberration (color blur). Chromatic aberration occurs due to the dispersion of light and the different wavelengths of light focusing on different positions, resulting in a red or purple fringing around the image. The optimum optical material to minimize chromatic aberration is fluorite crystal. 

    A fluorite crystal with extremely low dispersion characteristics is used for the convex lens of the TSN-883/884 PROMINAR models. In place of an ordinary optical glass lens, the concave lens paired with the fluorite crystal lens is made of glass with special dispersion properties to reduce the chromatic aberration to a further degree. 

  • Fluorite crystal

    Kowa uses the fluorite crystal exclusively in its flagship spotting scope and large binocular models. The fluorite used as make an optical lens is an artificially grown mono-crystal with "ultra-low dispersion", a characteristic that ordinary optical glass does not have. 

    It is an ideal lens material that almost completely eliminates chromatic aberration (color blur). The fluorite crystal produced by the sophisticated processing technology that Kowa has accumulated over the years guarantees the ultimate viewing experience.

  • Compact

    The telephoto lens design of using 5 lens elements in 4 groups has successfully shortened the overall length of the scope while keeping a large diameter objective lens without sacrificing optical performance. 

    The adoption of an inner focusing system has made the prism box light and compact and at the same time decreases the amount of image movement when compared to conventional prism focusing systems. 

    The highly achromatized objective lens makes the scope as compact as a 60mm class scope without sacrificing performance. 

  • Dual focus mechanism (Quick and fine focusing)

    The well established Kowa focus system has progressed to a new dual focus system. The quick focus, with a large and easy to turn knob, will focus from infinity to five meters in two revolutions. 

    The fine focus, with smooth movements and pinpoint accuracy, is extremely useful at high magnifications and for digiscoping systems. 

  • Eyepiece locking mechanism 

    Kowa's standard eyepiece bayonet mount has been passed down to these new spotting scopes with a new attractive feature. An eyepiece locking 

    mechanism has been added to the mount to prevent the eyepiece from getting lost or falling out unexpectedly. 

  • Magnesium alloy body 

    The magnesium alloy body made by a sophisticated molding process called thixotrophic molding has the feel and strength of a traditional metal body with decreased weight when compared to other large-diameter scopes. 

    The rugged structure can tolerate the severest conditions and provides confidence and a sense of security for the user. 

This combination of fluorite crystal and glass with special dispersion properties nearly eliminates chromatic aberration and redefines the standards of color brilliance. 

This technology is the result of many years of optical design and has realized great reduction in chromatic aberration, while maintaining a large diameter lens and high contrast images when compared with conventional models. 

The XD lens used in our TSN-883/884 PROMINAR models has characteristics similar to those of fluorite crystal to significantly reduce the chromatic aberration. All lenses are environmentally friendly Eco-Glass. (Eco-Glass is an environmentally friendly glass that does not contain lead or other harmful substances.)

All spotting scopes are waterproof to JIS protection class 7 and filled with dry nitrogen gas to prevent the lens from fogging. 

JIS 7 = Japanese Industrial Standard / class 7 = Protected against the effects of temporary immersion in water.

Loughborough GB Amateur birder - lover
Having used both a Zeiss 85 FL and a Swarovski 65HD, this Kowa 883 with 25-60x zoom is proving a simply wonderful birding scope: bright as can be, v-e-r-y wide and pin sharp to the edge, vivid contrast with natural colours. It is compact and not at all heavy, and balances beautifully on the tripod. It's already found me some great birds inc. hawfinch, crossbill, ring ousel and raven.
I cannot fault the scope on any way, even the case is both highly practical yet very modern in design. Well done Kowa.

Newcastle upon Tyne GB Keen birdwatcher and photographer.
Fantastic image quality.
Focus controls are easy to use and (whilst it's personal preference) easier than image controls that are the full telescope body diameter.
Good price but still a very expensive piece of kit.
No bad points.
