About China Star Optics Technology Co., Ltd. - Optical Lenses Supplier in China

China Star Optics Technology Co., Ltd. is based in China and currently lists eight distinct optical products. The catalogue includes projector lenses, wide‑angle lenses (including a 0.45× 52 mm variant), plano‑convex cylindrical lenses, standard plano‑convex lenses, window lenses, cemented lenses, and diffraction gratings. All items fall under the optical lenses segment, which is classified in HS chapter 90, heading 9001 for optical elements. The supplier’s portfolio therefore covers both imaging optics and precision diffraction components.

The eight products are presented without additional accessory equipment, focusing on core lens geometries and a grating type. The range spans lenses used in projection systems, wide‑field imaging, and optical instrumentation, as well as a grating suitable for wavelength separation. Each product aligns with typical optical‑component specifications such as focal length, diameter, surface accuracy, and coating options, which buyers evaluate against standards like ISO 10110 and IEC 60825. The supplier is listed as an imported tier with a harbor trust rating, indicating that trade transactions are mediated through established logistics channels.

Product Range and Specialties of China Star Optics Technology Co., Ltd.

The catalogue’s projector lens is typically offered in focal lengths from 20 mm to 200 mm, with antireflection (AR) coatings delivering transmission above 95 % in the visible spectrum. Wide‑angle lenses generally provide fields of view between 70° and 120°, and the 0.45× 52 mm variant is designed for compact imaging modules. Plano‑convex cylindrical and standard plano‑convex lenses are commonly supplied in diameters from 25 mm to 150 mm, with surface quality specifications of 0.1 λ (λ=632.8 nm) or better and surface figure tolerances of ±0.01 mm. Window lenses are usually made from optical glass such as BK7 or fused silica, offering thicknesses up to 20 mm and parallelism within 0.02 mm. Cemented lenses involve two glass elements bonded with optical cement, often meeting combined refractive‑index tolerances of ±0.001. Diffraction gratings are typically ruled or holographic, with groove densities ranging from 300 to 1200 lines/mm and efficiency above 80 % at the design wavelength. Industry standards for these items include ISO 10110 for surface and coating, and IEC 60825 for laser safety where applicable.

Trade and Export Information - China Star Optics Technology Co., Ltd.

China is a major exporter of optical components, and products classified under HS heading 9001 are regularly shipped to North America, the European Union, and Southeast Asian manufacturing hubs. Buyers in projection equipment, medical imaging, and semiconductor lithography often require compliance with ISO 10110, CE marking for EU markets, and FCC or UL listings for North American applications. Typical export packaging involves double‑wall cartons with foam inserts, moisture‑barrier bags for coated optics, and palletized loads sized for 20‑ft or 40‑ft containers.

Logistics for optical lenses prioritize vibration‑free handling and temperature‑controlled environments; many exporters use Incoterms CFR or CIF to cover freight and insurance to major ports such as Shanghai, Shenzhen, and Ningbo. Customs inspections frequently reference the optical‑lens HS sub‑heading 9001.10 for uncoated lenses and 9001.20 for coated lenses, and regulators may request test certificates confirming transmission, surface flatness, and coating durability. While China Star Optics does not list specific certifications, buyers should request copies of ISO 10110 compliance reports, coating process certifications, and, where required, CE Declaration of Conformity.

Sourcing from China Star Optics Technology Co., Ltd. - Buyer Guidance

When sourcing lenses from China Star Optics, buyers should obtain a detailed datasheet that lists focal length, diameter, glass type, surface accuracy, coating specifications, and transmission percentages. Requesting a sample unit for optical bench testing can verify surface figure, wavefront error, and AR coating performance against the supplier’s stated parameters.

In addition, ask for third‑party test reports such as ISO 10110 inspection certificates, laser‑safety classification (IEC 60825), and, for gratings, efficiency curves across the intended wavelength range. Verify that packaging includes protective desiccant packs and anti‑static bags, and confirm lead times - typically 4‑6 weeks for standard lenses and 6‑8 weeks for custom‑cut or cemented assemblies. Clarify the accepted Incoterms and arrange for pre‑shipment inspection if required by the importing country.

What optical lens types are listed in China Star Optics’ catalogue?

The catalogue includes projector lenses, wide‑angle lenses (including a 0.45× 52 mm version), plano‑convex cylindrical lenses, standard plano‑convex lenses, window lenses, cemented lenses, and a diffraction grating.

Are any industry standards referenced for these lenses?

The supplier’s products fall under the optical‑elements HS heading 9001 and are typically evaluated against ISO 10110 for surface and coating specifications and IEC 60825 for laser‑safety classifications.

How can a buyer obtain technical specifications before placing an order?

Buyers should request a product datasheet that details focal length, diameter, glass material, surface accuracy, coating type, transmission rate, and, for the grating, groove density and efficiency.

What documentation is commonly required for import clearance of optical lenses from China?

Importers usually need a commercial invoice, packing list, certificate of origin, and test reports confirming compliance with ISO 10110; a CE Declaration of Conformity may be required for EU shipments.

What are typical minimum order quantities and lead times for these optics?

Standard lenses are often available with an MOQ of one unit, while custom‑cut or cemented lenses may require an MOQ of 10 pieces; lead times range from four to six weeks for off‑the‑shelf items and six to eight weeks for customized orders.

How are the lenses packaged for international shipping?

Export packaging generally consists of optical‑grade foam inserts inside double‑wall cartons, with moisture‑barrier bags and anti‑static wrapping for coated lenses, stacked on pallets for container loading.

Which markets most frequently import these types of optical components?

Major importers include the United States, Germany, Japan, and South Korea, where the lenses are used in projection systems, medical imaging devices, precision instrumentation, and semiconductor equipment.
