China CNC Aspherical Glass Optics
The CNC aspherical glass optics are precision‑machined lenses offered in diameters from 5 mm to 200 mm and made from optical glass such as borosilicate or BK7. They meet a surface quality of 40‑20 and a flatness of 1/4 λ, ensuring minimal wavefront error. Each element is produced by CNC machining to achieve the aspherical profile required for high‑performance laser and imaging systems. The supplier lists the optics as suitable for integration into medical devices, semiconductor inspection tools and other scientific equipment.
In the optics industry, BK7 glass is a standard material because of its stable refractive index of about 1.5168 at the sodium D‑line. Typical aspherical lenses are specified for a wavelength transmission range of 400‑700 nm and carry an anti‑reflective coating that reduces reflectance to below 0.5 % at 550 nm. Tolerances on the radius of curvature are usually ±0.1 % and the scratch‑dig rating of 40‑20 is a common benchmark for precision optics. These typical values complement the supplier’s stated surface quality and flatness, giving buyers a clear reference point.
The lenses are purchased by OEMs that build laser‑based manufacturing equipment, research laboratories developing optical instrumentation, and manufacturers of high‑resolution imaging systems. Procurement can be arranged with flexible minimum order quantities and shipping terms such as CIF or FOB from major Chinese ports. Buyers should request the supplier’s ISO or CE test certificates and verify that the optics meet the 40‑20 surface specification before finalising the order. Payment is usually made by T/T against documentary evidence, following the standard trade practice for optical components.

Changchun Sunday Optoelectronics Co., Ltd is located at No 9576 Donghuan Road, Changchun, 130000, China. The company is listed in the harbour trust tier and currently shows a response rate of 0 % with no recorded average response time, indicating that inquiries may require follow‑up. Its profile states that it supplies CNC‑machined aspherical glass optics and does not provide additional corporate history, production capacity or client references.
The supplier’s listing highlights that the optics are exported globally and comply with ISO and CE certifications, although specific certificates must be requested from the company. No further details about factory size, workforce or years in operation are disclosed, so buyers should confirm any quality management system claims directly with the supplier before placing an order.
CNC aspherical glass optics are precision-manufactured optical elements used in laser systems, imaging equipment, and photonics applications. These lenses offer superior light聚焦 ability compared to spherical lenses, reducing spherical aberration in industrial and scientific instruments. Exported globally for integration into optical assemblies, medical devices, and semiconductor inspection equipment, with diameter ranges from 5mm to 200mm and surface quality meeting 40-20 standards.

Sourcing China CNC Aspherical Glass Optics from Changchun Sunday Optoelectronics Co., Ltd - China Import Guide
Before placing an order, verify the glass grade (BK7 or borosilicate) and request the ISO 9001 or CE test reports that certify the surface quality and flatness. Confirm that the supplier can provide a surface‑profilometer or interferometer report for each shipment, as these documents are essential for high‑precision applications.
Logistics should be clarified early: ask the supplier which port in China will be used for export, whether the terms are CIF or FOB, and the expected lead time, which typically ranges from four to six weeks for custom‑cut optics. Discuss payment conditions such as T/T against documents to align with standard international trade practice.
Upon receipt, arrange a third‑party inspection to check diameter, surface quality and coating performance. Request a detailed inspection report that includes measurements of flatness, scratch‑dig rating and transmission at the required wavelength. Keeping these checks in the procurement workflow helps ensure that the delivered optics meet the technical requirements of your end‑use.
