AI-Powered supplier vetting

SummaryThe supplier is a limited company offering night vision devices, multifunction thermal cameras, laser rangefinders, thermal cores, image intensifier tubes, and related electronic and optoelectronic products. It reports ISO9001:2015 and CE certifications, documented service procedures, complaint-handling and corrective-action procedures, and broad customization capability. Production information states annual output of 6,000,000 pieces for bulletproof vests, helmets, and plates, with peak-season lead time of one month and off-season lead times ranging from within 15 workdays to one month across the provided records. The supplier exports independently, serves multiple global markets, and has exported for four years. Evidence of financial records exists for 2022–2024, but no substantive financial results are provided. It lacks overseas warehouses, showrooms, agents, and branches, while reporting participation in IDEX 2025. No OEM service for popular brands is reported, although SDK availability indicates...

Supplier typeThe supplier is identified as a limited company. Its stated business scope covers electronic special materials, optoelectronic device manufacturing and sales, electronic measuring instruments, electronic components, and related electromechanical equipment, while its offered products include night vision devices, multifunction thermal cameras, laser rangefinders, thermal cores, and image intensifier tubes.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product compliance certification in both certification-related records. These provide explicit evidence of holding the stated management and product certifications.

After-Sales capabilityThe supplier reports written procedures and followed records for corrective and preventive actions and customer complaint handling, supporting a documented after-sales process. However, it has no overseas warehouse, showroom, agent, or branch, and reports zero countries with overseas services, which limits demonstrated overseas service coverage.

R&D capabilityThe supplier reports research and development capability with an available SDK, and its business scope includes mechanical equipment research and development and optoelectronic manufacturing. These records support technical development capability, although no R&D scale, patents, or completed innovations are provided.

Production capacityThe supplier reports annual production of 6,000,000 pieces for bulletproof vests, helmets, and plates, serves multiple export markets, and states peak-season fulfillment of one month. Off-season lead time is reported as within 15 workdays in one record and one month in another, so capacity is evidenced but timing data is not fully consistent.

Customization capabilityThe supplier explicitly reports customization from samples, designs, full customization, minor customization, and flexible customization. This is direct evidence of a broad range of customization options.

Product Q&A

Q:Can I use this polarizer at other wavelengths?

While the Brewster angle is slightly dependent on the refractive index (which varies with wavelength), these polarizers perform excellently across the visible to NIR spectrum. For specific ultra-precision tasks (e.g., 355nm or 1550nm), we can customize the coating and angle.

Q:How does this compare to a Wire-Grid or Glan-Thompson polarizer?

Unlike absorbing or birefringent polarizers, Brewster Polarizers are thin-film-based, meaning they have a much higher damage threshold and lower cost. They are the preferred choice for high-power industrial lasers where heat dissipation is a concern.

Q:What is the warranty period for this product?

We provide a 1-year warranty for this product.

Q:What are the available material options?

The polarizer is available in K9 (BK7) or UV Grade Fused Silica (Quartz) materials.

Q:Is customization available for this product?

Yes, the shape is customized, and we offer full customization options including from samples or designs.
