We have provided customized optical precision machining services to Aerospace Science and Technology Group, Huawei, ZTE, BYD and other enterprises. Our product qualification rate across all optical components stands at 99.98%.
Our optical machining workshop maintains constant temperature at ±0.5°C. This stability is essential for Optical Component Precision Machining With Ultra Accuracy, as thermal expansion of even 0.1°C can alter dimensions by several micrometres on large optical components.
Humidity is maintained at 40‑60% to prevent moisture absorption in optical materials and to maintain consistent machine performance. Controlled humidity also reduces the risk of surface oxidation on finished optical components.
Class 1000 dust‑free level ensures that particles do not contaminate optical surfaces during machining and inspection. Particle contamination can cause scratches, digs, and scatter that degrade optical performance.
Our anti‑vibration foundation maintains vibration amplitude below 0.1μm. This is critical for Optical Component Precision Machining With Ultra Accuracy, as even micro‑vibrations can introduce tool marks and surface errors that are visible under interferometric inspection.
Every optical component undergoes interferometric measurement to verify surface form accuracy. Our Zygo interferometer provides surface maps with λ/20 resolution, ensuring compliance with optical prescriptions.
Profilometry is used to verify surface roughness across the entire optical aperture. We document Ra, Rz, and other roughness parameters to confirm that Optical Component Precision Machining With Ultra Accuracy meets your specifications.
