Parameter
Our glass aspheric lenses are manufactured with high precision, offering diameters from 5 to 600 mm and surface quality up to 10‑5. Surface irregularity is controlled to λ/4 (632.8 nm), with PV ranging from 0.5 to 10 µm, fully customizable per client specifications. We provide optical-grade JGS1 glass and infrared materials, with single-layer or multi-layer AR coatings spanning 350–1585 nm, or custom wavebands as needed.
