Kowa TP-105FT Protective Filter for TSN-99 Series
The Kowa TP-105FT Protective Filter is designed specifically for the TSN-99 PROMINAR and provides essential protection for its valuable pure fluorite crystal objective lens. Featuring oil and water repellent coatings, it helps keep the lens cleaner in harsh outdoor conditions such as sand, salt spray, and rain. By shielding the front lens from knocks, scratches, and other damage, this filter helps preserve optical performance, reduce the risk of costly repairs, and prolong the life of your spotting scope.
The Kowa TP-105FT Protective Filter is a smart and practical accessory designed specifically for the Kowa TSN-99 PROMINAR spotting scope. Built to protect the valuable pure fluorite crystal objective lens, it helps guard the most delicate part of your optic from everyday hazards that can seriously affect performance.
Whether you are using your scope on the coast, in dusty ground conditions, or in other demanding environments, this filter adds an extra layer of defence against sand, salt, moisture, knocks, and sharp contact. The oil and water repellent coatings also help keep the front element cleaner, making maintenance easier and helping preserve image quality in the field.
Damage to an objective lens can be one of the most expensive issues to put right, especially on a premium fluorite model. As front lens damage is not covered by the manufacturer’s warranty, fitting a protective filter is a simple way to reduce the risk of costly repairs and extend the life of your spotting scope. For TSN-99 owners, the Kowa TP-105FT is a sensible investment that helps protect both the performance and long-term value of your optic.
In the box, you receive the 105mm filter and an instruction manual. This product is covered by the standard Kowa 2 Year Warranty.
