Coating Quality

• Adhesion Test: The coating meets the MIL-C-675C military standards for adhesion. The test involved applying a tape compliant with LT-90 specifications to the lens film. After attaching and removing the tape three times, no blistering or peeling occurred.
• Temperature Test: According to MIL-C-675C specifications, test pieces were subjected to temperatures of -62±1°C and 71±1°C. After allowing the test pieces to return to room temperature (16°C-32°C) for two hours, the adhesion test was repeated, confirming no detachment of the film.
• Abrasion Resistance Test: In compliance with MIL-C-675C and CCC-C-440 standards, the abrasion resistance test used a gauze tester applying a force of 1.0 lbs (0.45 kg) for 25 cycles with no damage to the film surface.
• Humidity Test: The test followed MIL-C-675C criteria, placing the test piece in a temperature and humidity chamber at 49±2°C with 95% to 100% humidity for 24 hours. Afterward, the film remained intact with no visible defects.
• Solvent and Cleaning Test: Following MIL-C-675C specifications, test pieces were exposed to acetone and alcohol at room temperature for 10 minutes each. After drying and cleaning with alcohol-soaked cotton cloths, no signs of damage or peeling were observed.
• Salt Spray Test: After 100 hours in a 35°C environment with a 5% saltwater concentration, no damage occurred to the film, confirming its resilience in corrosive environments.
