Import Broadband Antireflection Film — Buy in Bulk from Supplier in China

This broadband antireflection film from Taiyo Optics (Dongguan) Corp. is an optical coating designed to suppress surface reflection and maximise light transmission across the visible spectrum. The supplier specifies reflection below 1.3% at normal incidence (0 degrees) across a 400 nm wavelength reference point. The film targets applications in electronics displays, automotive glass, and solar panels where glare reduction and transmission efficiency are critical. Construction details such as substrate material, coating layer count, and deposition method are not disclosed. Physical dimensions including roll width, roll length, and film thickness are absent from the source data and require direct confirmation with the supplier.

Antireflection films in this performance category are typically manufactured through vacuum deposition or wet-coating processes, applying alternating layers of high and low refractive index dielectrics such as magnesium fluoride, silicon dioxide, titanium dioxide, or niobium pentoxide. A reflection below 1.3% at single wavelength or narrow band implies either a single-layer porous silica approach with limited broadband performance, or more likely a multi-layer stack with optimised thickness for the specified 400 nm point. Buyers should clarify whether the sub-1.3% figure applies across a broad band (for example, 400-700 nm) or at a single wavelength, as the term 'broadband' in the product name suggests wider coverage than the specification confirms. Typical substrate options include PET, TAC, PMMA, or glass, with hard coats and pressure-sensitive adhesive layers as optional additions.

Primary end users include LCD and OLED display manufacturers, automotive tier-one suppliers integrating anti-glare solutions into instrument clusters and head-up displays, and solar panel producers seeking front-surface transmission gains. The film's scratch and environmental resistance claims suggest a hard-coated surface, though pencil hardness, abrasion test method (for example, ASTM D1044 Taber or steel wool), and humidity exposure data are not provided. Packaging, MOQ, lead time, and pricing are not stated. Buyers should request spectral transmission curves across 380-1100 nm, adhesion test results (cross-hatch ASTM D3359), and thermal stability data for lamination processes before prototype qualification.

Taiyo Optics (Dongguan) Corp. is located at No. Xianglong Road, Shilong Town, Dongguan, Guangdong Province, China, postal code 523326. The company holds imported supplier tier and harbour trust tier designations. The response rate is recorded as 0.00% with zero average response hours, suggesting that initial contact may require multiple attempts or alternative channels beyond the platform messaging system. No establishment year, registered capital, factory floor area, or employee count is disclosed in the available profile.

The supplier operates in the optical components sector with a product range centred on antireflection and optical functional films. The profile references ISO certification without identifying the specific standard, certifying body, or scope of certification. Buyers should request a current certificate copy and verify validity through the issuing accreditation body. Given the technical nature of antireflection coatings and the precision required for display and optical applications, a factory audit or third-party inspection is advisable before committing to volume orders, particularly to confirm cleanroom classification, coating chamber capability, and spectrophotometer calibration traceability.
