Kowa TP-72FT 72mm Objective Lens Protection Filter
The Kowa TP-72FT is a 72 mm objective lens filter that provides essential protection for the pure fluorite crystal lenses of Kowa's TSN-66A and TSN-66S PROMINAR spotting scopes. Its oil and water repellent coatings make it easy to clean, and the filter helps protect the objective lens from accidental damage, which is not a defect covered by warranty.
Essential 72mm Protection for Kowa TSN-66A & TSN-66S Scopes
The objective lens is the most critical and expensive component of your spotting scope. Harsh environments (such as sand and salt at the coast), an accidental fall from a tripod or contact with a sharp object can cause irreparable damage to the lens and its coatings. The TP-72FT is a 72 mm filter that fits the filter ring and threads directly onto the front of your Kowa TSN-66A or TSN-66S, acting as a sacrificial barrier.
This filter guards against a costly objective lens replacement; accidental damage is not a defect in materials or workmanship, so it is not covered by warranty. Its coatings repel oil and water, making it easy to clean, and Kowa says a protective filter drastically reduces the risk of objective lens damage, prolonging the life and optical clarity of your scope.

Which Kowa scopes does the TP-72FT filter fit?
Kowa lists the TP-72FT filter for the Kowa TSN-66A and TSN-66S PROMINAR spotting scopes, which feature a 72 mm filter thread on the objective lens housing.
If I'm observing seabirds at the coast with my TSN-66S, how does the TP-72FT help?
Kowa names sand and salt at the coast among the hazards to an objective lens. With the TP-72FT fitted, salt spray lands on the filter instead of the objective lens, and its oil and water repellent coatings make the filter easier to clean.
I accidentally touched the objective of my TSN-66A. Would the TP-72FT have helped?
Yes. The oils from your skin can be difficult to clean and can damage delicate lens coatings over time. With the TP-72FT filter installed, any fingerprints would be on the filter's coated surface, which is specifically designed to repel oils and be cleaned easily and safely, rather than on the objective lens itself.
Is damage to my objective lens covered by the Kowa warranty?
No. The Kowa Limited Lifetime Warranty covers defects in materials and workmanship. Accidental damage such as a scratched or chipped objective lens is not a defect, and damage from abuse or misuse voids the warranty. Kowa recommends a protective filter such as the TP-72FT to reduce the risk of this kind of damage.
