General Optics conducts comprehensive durability testing to ensure that optical coatings and components maintain reliable performance even under the most
demanding conditions. All tests are carried out in accordance with ISO and MIL-STD standards, verifying resistance to mechanical stress, environmental changes, and chemical exposure.
Test Categories
- Abrasion & Adhesion – Verifies surface wear resistance and coating adhesion strength
- Temperature & Humidity Cycling – Stability under conditions ranging from -80°C to +90°C and 0–100% relative humidity
- Chemical Resistance & Cleanability – Evaluation of durability against solvents and cleaning processes
- Salt Fog Test – Corrosion resistance under 35% saltwater exposure
- LIDT (Laser-Induced Damage Threshold) Testing – Ensures coating reliability under high-power laser operation
Durability test procedure
The procedure includes: abrasion test → adhesion test → temperature test → abrasion test → adhesion test → humidity test → abrasion
test → adhesion test → solubility & cleanability test (3 cycles) → abrasion test → adhesion test
All coatings verified under ISO & MILSTD standards for maximum reliability in extreme environments.
