Why Choose Our Glass Aspheric Lenses
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.

FAQ - Glass Aspheric Lens
Q: What materials and coatings are available?
A: Standard material is JGS1 optical glass. Infrared materials are available on request. Coatings include single-layer MgF2 and multi-layer AR coatings from 350–1585 nm, with custom wavebands possible.
Q: What are the minimum and maximum diameters and tolerances?
A: Diameters range from 5–600 mm. Standard diameter tolerance is +0.00 / -0.02 mm, thickness tolerance +0 / -0.02 mm. Custom tolerances can be made per drawings.
Q: How is lens surface precision ensured?
A: Lenses are manufactured using CNC and traditional polishing, plus MRF for ultra-precision. Each lens is tested for PV, surface roughness, and wavefront error, with reports provided.
Q: Can you provide samples or small-batch production?
A: Yes, sample lenses are available for evaluation before mass production to ensure batch consistency.
Q: What applications are these lenses suitable for?
A: Thermal imaging, laser collimation, OEM optical modules, analytical and measurement instruments.
Q: Can lenses be customized for specific coatings or wavebands?
A: Yes, we can produce lenses with custom AR coatings, wavebands, and PV tolerances per your specifications.
Q: How fast is lead time for custom orders?
A: Lead time depends on diameter, coating, and quantity. Small samples can be shipped within 2–3 weeks; mass production lead times will be quoted per order.
