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

Vy Optics Photoelectric Technology Co., Ltd. is a China-based supplier operating in the precision optics segment, with an active catalogue of 5 products grouped under the Optical Lenses category. The listed range covers specialised optical components rather than commodity optics, including a fisheye lens, a wedge prism, optical windows, a ball lens, and a LiNbO3 (lithium niobate) lens. These items are the type of components used in laser systems, imaging modules, electro-optic instrumentation, and research-grade optical assemblies where specific material properties and surface geometries are required. As an imported supplier on the platform, the company is positioned to serve international B2B buyers sourcing niche photonic components from the Chinese optics manufacturing cluster. The product mix reflects a focus on custom-shaped and material-specific optics rather than standard spherical or plano-convex lenses. Wedge prisms and ball lenses are typically used for beam steering, alignment, and fibre-optic coupling, while optical windows serve as protective or transmissive interfaces in laser and sensor housings. The LiNbO3 lens in the catalogue points to electro-optic and nonlinear optics applications, since lithium niobate is a standard crystal for modulators, Q-switches, and frequency-conversion devices. Buyers reviewing the listing should treat the 5 active products as the verifiable scope of what is offered, with any additional capability to be confirmed directly through technical enquiry.

Product Range and Specialties of Vy Optics Photoelectric Technology Co., Ltd.

The catalogue of Vy Optics Photoelectric Technology Co., Ltd. covers five distinct optical components. The fisheye lens is a wide-field imaging optic, typically specified by focal length, image circle diameter, and maximum angle of view, and is commonly built from crown or flint glass or from optical-grade polymers for compact applications. The wedge prism is a tilted-plane optical element used to deviate a beam by a controlled angle, with the deviation defined by the wedge angle and the refractive index of the substrate material; standard offerings use BK7, fused silica, or UV-grade calcium fluoride depending on the working wavelength range. Optical windows in this category are flat-parallel plates specified by diameter or rectangular dimensions, thickness, parallelism, surface flatness (commonly expressed in fractions of a wavelength such as lambda/10 or lambda/20), and scratch-dig surface quality grades such as 40-20 or 20-10 per MIL-PRF-13830. Ball lenses are small spheres used for fibre coupling, endoscopy, and barcode scanning, typically manufactured from BK7 glass, sapphire, or ruby, with diameters ranging from sub-millimetre up to about 10 mm and specified by refractive index and ball diameter tolerance. The LiNbO3 lens is a lithium niobate component, a birefringent crystal widely used in electro-optic modulators, acousto-optic devices, and frequency-doubling setups, and is normally specified by crystal orientation (commonly x-cut or z-cut), surface polish quality, and AR coating wavelength. Across all five items, buyers should expect surface coatings such as anti-reflection (single-layer MgF2 or broadband multilayer), partial反射, or dichroic coatings to be defined per order.

Trade and Export Information - Vy Optics Photoelectric Technology Co., Ltd.

Optical components from China are typically exported under HS code 9002 (lenses, prisms, mirrors and other optical elements, of any material, mounted or unmounted) and, for finished optical instruments, HS 9001 or 9013, while lithium niobate wafers and crystal elements may additionally fall under HS code 9002 or, depending on classification, 3818 for doped semiconductor or crystal materials. Typical destination regions for Chinese precision optics include the European Union, North America, Japan, South Korea, and the broader ASEAN manufacturing base, where the components feed into laser equipment, medical imaging, semiconductor inspection, and photonics R&D. Standard Incoterms for these goods are usually EXW, FOB Shanghai or FOB Shenzhen, with CIF and DAP used for smaller, higher-value shipments that consolidate by air rather than by 20 ft or 40 ft container. For optical components in this category, buyers and customs authorities commonly expect compliance with REACH (EU) for chemical substances used in coatings and adhesives, RoHS for restriction of hazardous substances in electronic and electrical equipment, and CE marking where the optics are integrated into regulated instruments. Optical-grade substrates such as BK7 and fused silica are generally accepted as standard, while specialty crystals like LiNbO3 require documentation of crystal orientation, stoichiometry, and optical homogeneity. Inspection of such parts typically follows ISO 10110 for the preparation of drawings and standard presentation of optical elements, which defines tolerances for surface form, material homogeneity, and centring. Packaging for these components is normally anti-static foam-lined cases or vacuum-sealed bags within hard-shell optical cases, with desiccant and shock indicators for international transit, and export documentation usually includes a commercial invoice, packing list, certificate of origin, and where required a material safety data sheet for coated or crystal products.

Sourcing from Vy Optics Photoelectric Technology Co., Ltd. - Buyer Guidance

Buyers approaching Vy Optics Photoelectric Technology Co., Ltd. should anchor their enquiry on the technical specification sheet rather than on catalogue images alone. For each of the five listed items, request the substrate material (BK7, fused silica, sapphire, LiNbO3 cut orientation), key dimensions with tolerances, surface flatness and scratch-dig grade per ISO 10110 or MIL-PRF-13830, and the coating specification including wavelength range, reflectivity per surface, and damage threshold where laser use is intended. For the LiNbO3 lens in particular, confirm the crystal orientation, AR coating wavelength, and any intended electro-optic or nonlinear application, since these drive both cost and lead time. It is standard practice in this category to request a sample or a first article for measurement before issuing a volume order, and to ask for a test report covering transmission curves, wavefront error, and surface metrology. Buyers should also confirm which certifications the supplier actually holds and which it can provide on a per-shipment basis, such as RoHS and REACH compliance statements, a certificate of origin, and inspection reports aligned to ISO 10110. MOQ, lead time, and packaging format (anti-static foam-lined optical case, vacuum bag, individual serial labelling) should be agreed in writing before order confirmation, since precision optics are typically built to order rather than stocked. Verifying these points up front is the most reliable way to align the supplier's output with the tolerances required by laser, imaging, or electro-optic system integrators.

What product categories does Vy Optics Photoelectric Technology Co., Ltd. supply?

The supplier lists 5 active products under the Optical Lenses category, covering a fisheye lens, a wedge prism, optical windows, a ball lens, and a LiNbO3 lens. These are specialised optical components rather than commodity camera lenses, and are typically used in laser, imaging, and electro-optic assemblies.

Which HS code applies to the optical components in this catalogue?

Optical elements of this type, including lenses, prisms, and windows, are generally classified under HS code 9002. Lithium niobate crystal components may fall under 9002 or, depending on the customs authority's treatment, under 3818 for processed crystal materials, so the exact classification should be confirmed with the supplier and customs broker.

Which specifications should I request before ordering a wedge prism or ball lens?

Request the substrate material (BK7, fused silica, sapphire), key dimensions with tolerances, wedge angle or ball diameter, surface flatness expressed in fractions of a wavelength (for example lambda/10), scratch-dig grade per MIL-PRF-13830 (such as 40-20 or 20-10), and the anti-reflection coating wavelength range. For ball lenses, also confirm the refractive index and sphericity tolerance, since these directly affect fibre-coupling efficiency.

What should I confirm about the LiNbO3 lens in the catalogue?

Confirm the crystal cut orientation (commonly x-cut or z-cut), surface polish quality, AR coating wavelength, and the intended application such as electro-optic modulation or frequency conversion. Lithium niobate is a birefringent crystal, so optical homogeneity and stoichiometry documentation should be requested along with a transmission curve over the working wavelength band.

Which certifications and documents are typically required for importing these optics from China?

Buyers in the EU commonly require REACH compliance for coating materials and RoHS compliance for restricted substances, plus a certificate of origin and commercial invoice. Inspection reports aligned to ISO 10110 for optical element drawings and tolerances are standard, and a material safety data sheet may be requested for coated or crystal products.

What is the typical MOQ and lead time for custom optical components?

Precision optics of this type are usually built to order rather than held in stock, so MOQ is often set at prototype quantity (1 to 10 pieces) for first articles and at modest batch sizes for production runs. Lead time depends on substrate availability and coating complexity, but custom coated optics from Chinese suppliers typically ship within 3 to 6 weeks after drawing approval.

How are optical components typically packaged for international shipment?

Individual optics are normally wrapped in lens tissue or vacuum-sealed in anti-static bags, then placed in foam-lined optical cases with desiccant and shock indicators. Hard-shell transit cases are used for higher-value items such as LiNbO3 crystals and coated prisms, and each part is usually serial-labelled for traceability on receipt.

Which Incoterms are standard for sourcing optical components from China?

EXW and FOB (commonly FOB Shanghai or FOB Shenzhen) are the most frequently used Incoterms for Chinese optics exporters, with CIF and DAP applied for smaller, higher-value air-freight shipments. The chosen Incoterm should be agreed in writing along with the packing list format and the documentation set to be supplied with each shipment.
