NiSi Cinema True Protector Explosion-Proof Filter for Cooke (LP-10510)

The NiSi True Protector for Cooke lenses is a screw-in safety filter built to keep a Cooke lens's front element protected at all times, using a shatter-proof coating that keeps glass fragments together on impact instead of shattering outward. Because it's water white glass with no added color or contrast, it stays on the lens permanently without requiring exposure adjustment. A cinema edge seal adds durability, and the filter remains compatible with the lens cap that ships with the Cooke lens.

• Shatter-proof Explosion-Proof Layer: Keeps glass fragments together on impact rather than shattering like standard glass.
• No added coloration or contrast: Water white glass means no exposure adjustment is needed when it's mounted.
• Double-sided anti-reflective waterproof coating: Reduces reflections with no loss in sharpness.
• Cinema edge seal: Adds durability for repeated on-set use.
• Compatible with Cooke S6i, 5i, and S7A primes: Fits specific focal lengths across all three Cooke lens lines, and works with the included Leitz lens cap.
