About Jilin Tianhua Opto Electrical Technology Development Co., Ltd. - Optical Lenses Supplier in China

Based in China, Jilin Tianhua Opto Electrical Technology Development Co., Ltd. lists ten active optical components in its catalogue. The product portfolio is confined to optical lenses and prisms, covering plano‑concave, plano‑convex, bi‑convex, bi‑concave, as well as cylindrical variants of the plano‑convex and plano‑concave designs. Additional items include LED prisms, equilateral prisms, dove prisms and penta prisms. Each entry is presented under the single top category of Optical Lenses. The catalogue reflects a focused range of precision glass and polymer optics.

The listed lenses are typical in applications such as imaging systems, laser collimation, fiber‑optic coupling and industrial inspection. Standard specifications for these types include focal lengths ranging from a few millimetres to several centimetres, surface accuracy of λ/4 or better, and scratch‑dig grades of 40‑20 for glass optics. Prisms are commonly supplied with angular tolerances within ±0.1°, transmission above 90% in the visible range, and are compatible with LED illumination. While the supplier does not disclose material composition, optical components of this class are usually fabricated from BK7, high‑index glass or optical‑grade polymers. The catalogue does not provide HS‑code information, so buyers should verify the appropriate HS‑code (e.g., 9001) during customs clearance.

Product Range and Specialties of Jilin Tianhua Opto Electrical Technology Development Co., Ltd.

Jilin Tianhua’s catalogue comprises ten distinct optical parts: plano‑concave, plano‑convex, bi‑convex, bi‑concave lenses, cylindrical versions of plano‑convex and plano‑concave lenses, and four prism types (LED, equilateral, dove and penta). In the optical market, such lenses are commonly produced from BK7 crown glass, high‑index flint glass, or acrylic polymer, with diameters from 10 mm up to 100 mm and focal lengths from - 50 mm to +200 mm. Typical surface quality for precision lenses is specified as λ/4 (633 nm) wavefront error and a scratch‑dig of 40‑20 for glass, while polymer lenses may meet 60‑40. Prisms are usually manufactured from the same material families, with angular accuracy of ±0.05° for equilateral and dove prisms and ±0.1° for penta prisms, and are often coated with anti‑reflective layers to achieve transmission above 95 % across 400 - 700 nm.

Trade and Export Information - Jilin Tianhua Opto Electrical Technology Development Co., Ltd.

China is a major exporter of optical components, with the United States, European Union members and Southeast Asian manufacturers representing the largest demand. Optical lenses and prisms fall under HS chapter 90, typically HS 9001 for lenses and HS 9002 for prisms, and are subject to import inspections for compliance with IEC 60825 (laser safety) and ISO 10110 (optical component specifications). Buyers frequently require CE marking for EU shipments and may request ISO 9001 quality management certification from the supplier. Standard packaging includes anti‑static foam inserts within double‑wall cartons, sized for 20‑ft or 40‑ft containers depending on order volume. Common Incoterms are FOB Shanghai or CIF Los Angeles, with freight handled by air for small batches or sea for bulk shipments.

Sourcing from Jilin Tianhua Opto Electrical Technology Development Co., Ltd. - Buyer Guidance

Importers should request a detailed data sheet that lists material type, diameter, focal length, surface accuracy, transmission and coating specifications for each lens model. A certificate of conformity to ISO 10110 or a test report showing wavefront error and scratch‑dig grade is standard practice before order confirmation. For prisms, buyers typically ask for angular tolerance certificates and transmission test results at key wavelengths. Sample lenses or prisms can be ordered to verify dimensional tolerances and coating performance; lead times for custom‑cut optics in China range from 2 weeks for standard sizes to 6 weeks for specialty orders. Verify the supplier’s ability to provide required certifications such as CE or ISO 9001, and confirm packaging details to prevent damage during transit.

What types of lenses does the supplier offer?

The catalogue lists plano‑concave, plano‑convex, bi‑convex, bi‑concave, and cylindrical versions of plano‑convex and plano‑concave lenses.

Are the lenses made from glass or plastic?

The supplier does not specify material, but lenses in this category are normally produced from BK7 or high‑index glass, or from optical‑grade polymers such as acrylic or polycarbonate.

Which prisms are available and what are their typical tolerances?

Available prisms include LED prisms, equilateral prisms, dove prisms and penta prisms; industry practice expects angular tolerances of ±0.05° to ±0.1° and surface transmission above 90 % in the visible range.

What documentation should a buyer request before purchasing?

Buyers should ask for a product data sheet, material certification (e.g., ISO 10110 compliance), wavefront error or scratch‑dig test reports, and, if required, CE or ISO 9001 certificates.

What are the common packaging methods for these optical components?

Optical components are typically packed in anti‑static foam inserts inside double‑wall cartons, with pallets for sea freight; packaging is designed to protect against mechanical shock and moisture.

Which HS codes are normally used for customs clearance of these items?

Lenses are generally classified under HS 9001 and prisms under HS 9002, though the exact code depends on material and end‑use.

What are typical lead times and minimum order quantities?

Standard stock lenses can be shipped within 10‑14 days, while custom‑cut lenses or specialty prisms usually require 4‑6 weeks; minimum order quantities are often set at 100 pieces per item, but may vary with size and material.
