The Kowa TP-105FT Protective Filter for TSN-99 Series helps to protect the pure fluorite crystal objective lenses of the Kowa TSN-99 Prominar. Damage to the front objective lens can drastically reduce the optical performance of your scope and is one of the most costly repairs to rectify, especially if you own a Kowa pure fluorite crystal model. Often the only option is to completely replace the front objective lens at great cost. Unfortunately, this type of damage is not covered by the manufacturer's warranty, so using this filter helps avoid a possible expensive and lengthy repair.
