The Kowa 88mm PROMINAR Pure Fluorite Spotting Scope is a world-class spotter that redefines the standards of color brilliance, sharpness, and brightness. Seeing nature represented true to life can be one of the most engaging experiences we can ever hope to enjoy. For decades, it has been the passion, drive, and goal of PROMINAR optical engineers to always deliver this natural spectacle to the observer in glorious detail through our optics.

New Optical Coatings

Kowa engineers have improved the unique optical coatings applied not only to the lenses but also to the prism in the new TSN-88 PROMINAR spotting scope series. The new TSN-88 PROMINAR series features an 88mm pure fluorite crystal objective lens, the true optical powerhouse at the heart of all PROMINAR flagship optics. This unique fluorite crystal convex lens, only found in PROMINAR spotting scopes, when combined with a concave lens featuring our newly developed optical coatings, redefines the standards of color brilliance. This special combination not only eliminates chromatic aberration which is one of the major causes of deterioration of viewing quality but also increases resolution, contrast, and low light performance even at the highest levels of magnifications.

Small Changes that Make a Huge Difference

In addition to the optical enhancements, the new TSN-88 PROMINAR series benefits from some clever upgrades to improve your experience out in the field. A new dual tripod mounting system allows you to connect the scope to a tripod mounting plate using two securing screws. This subtle change can be a game changer when spending endless hours out in the field. No more having to readjust or tighten your scope to the tripod. Ultimate security, stability, and mobility all day long. The spotting scope includes a new detachable aiming site that can be fixed onto the accessory collar to assist in locating your subject more rapidly. The lens hood also features a newly designed built-in aiming site as a further visual aid. Protecting your TSN-88 PROMINAR has never been easier. A newly designed 95mm filter thread that is placed on the actual body of the scope can be utilized to connect the TP-95FT filter to protect the 88mm objective lens from dust, dirt, grease, and other foreign objects. The repositioning of the filter thread to the main body of the scope eliminates a cavity between the objective lens and filter, further reducing the risk of unwanted materials settling on the objective lens and eliminating lens flare. A smooth twist sun-shade helps to eliminate glare from the sun and reduces the exposure of the objective lens to elements such as moisture, grit, and sand. The objective lens has further protection with Kowa’s unique KR coating which actively repels dirt, moisture, and dust from building up on the surface. The new TSN-CV88A eyepiece protection cap now features a new twist-up design giving you full eye-relief functionality whilst protecting the lens of your chosen eyepiece from the elements.

Tougher and Lighter

The aluminum barrel formerly used on the TSN-880 series has now been upgraded meaning the new TSN-88 PROMINAR benefits from a full 100 percent magnesium alloy body. This sophisticated alloy offers all the strength benefits of metal whilst retaining a lightweight body. The outer body is fully sealed to protect it from the elements. 100 percent waterproof and nitrogen filled. As well as being built to last a lifetime, the TSN-88 PROMINAR is now even lighter and stronger.

Engineered with Precision and Ease of Use

The dual focus system is one of the defining features of our flagship spotting scopes, highly engineered to give ultimate control, the TSN-88A PROMINAR is no exception.
