4. Coating Quality

• Adhesion Test: The filters undergo an adhesion test compliant with MIL-C-675C military standards. This test involves applying a tape that meets LT-90 specifications onto the lens film layer. After three vertical removals, the coating shows no blistering or peeling.
• Temperature Test: In accordance with MIL-C-675C standards, test pieces are exposed to temperatures ranging from -62±1°C to 71±1°C. After maintaining the pieces at room temperature for two hours, the adhesion test confirms no detachment of the film.
• Abrasion Resistance Test: Conforming to MIL-C-675C and CCC-C-440 standards, an abrasion resistance test is performed with a gauze tester applying a minimum force of 1.0 lbs (0.45 kg). This process is repeated 25 times, ensuring no damage to the film surface.
• Humidity Test: The test piece is subjected to 24 hours in a chamber with a temperature of 49 ±2°C and 95%-100% humidity. The film remains intact with no peeling, scratches, or defects.
• Solvent and Cleaning Test: Following MIL-C-675C standards, the filters are exposed to acetone and alcohol at room temperature for at least 10 minutes. After cleaning with alcohol-soaked cotton cloths, no signs of peeling or scratches are observed on the film surface.
• Salt Spray Test: The filters are exposed to a 35°C environment with a 5% saltwater concentration for 100 hours, with no damage observed to the film.
