What is the refractive index of borosilicate glass?

The refractive index of borosilicate glass is n=1.51.

How should the photosensor be cleaned after soldering?

Using no-clean solder is recommended to avoid resin swelling or melting. If cleaning is necessary, gently wipe with a cotton swab moistened with ethanol, using a new swab each time to prevent scratches.

Do some photodiode products support lead-free solder?

Yes, we provide products that support lead-free solder. Soldering methods vary by product, so please contact our sales office for specific details.

AI-Powered supplier vetting

SummaryEMI International is a China-based trading company supplying electronic and related technology products. It reports more than 45 years of experience, ISO 9001:2015 certification, over 10 production lines, inventory capability, exports to multiple regions, and lead times within 15 workdays in both peak and off-peak periods. Its R&D offering includes multiple forms of customization, new-product activity during the past year, ODM services, and OEM services for known brands. However, it has fewer than five quality-control staff, no overseas branches, warehouses, or showrooms, and lacks written procedures or records for supplier approval, corrective actions, complaint handling, and service-capability assessment. R&D engineer experience, customer cases, and financial credibility cannot be reliably established from the provided information.

Supplier typeThe supplier identifies itself as a China-based electronic components supplier and is classified as a trading company. Its stated scope covers technical development and sales of electronic, communication, security, software, lighting, solar, smart-home, and related products.

CertificationsThe supplier explicitly reports ISO 9001:2015 certification and states that quality assurance exists within its quality-control processes. No additional certifications are documented.

After-Sales capabilityThe supplier has participated in an offline Germany exhibition and provides inventory capability, but it has no overseas agents or branches, overseas warehouses, or overseas showrooms. Complaint handling and corrective/preventive action have no written procedures or records, indicating a documented after-sales-service weakness.

Financial creditThe supplied financial record reports the last year as 2025 but shows zero operating revenue, operating cost, and gross profit. These figures do not establish positive operating performance or financial strength, although the provided data is insufficient to assess broader financial credibility.

R&D capabilityThe supplier reports new products during the past year, ODM services, and multiple customization modes. However, it has no available SDK, and total R&D-engineer experience is not provided, so innovation capability is supported in product development but not comprehensively documented.

Production capacityThe supplier reports more than 10 production lines, inventory capability, exports to Eastern Europe, North America, Eastern Asia, and Western Europe, and lead times within 15 workdays in both peak and off-peak seasons. Its outsourcing procedures and manufacturing-capacity contracts are unknown, so production governance is only partially evidenced.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also reports ODM service availability, providing direct evidence of broad customization support.

Product Q&A

Q:What factors determine photodiode response speed?

Response speed is determined by CR time constant, carrier diffusion time, and carrier transit time. Long-wavelength light causes slower response due to longer diffusion time. Speed can be improved by selecting lower terminal capacitance, reducing load resistance, or applying reverse voltage.

Q:Are areas other than the photosensitive area sensitive to light?

Yes, areas such as gaps between elements are sensitive to light, but their sensitivity does not match the effective photosensitive area. Light incident here can generate noise and delay response speed.

Q:How can noise from non-photosensitive areas be eliminated?

Noise can be eliminated by focusing light to a small spot, light-shielding the areas, or forming an aluminum or black light-shielding film on the chip's non-photosensitive areas.

Q:What is the value of the photodiode's series resistance (Rs)?

The series resistance (Rs) is typically a few ohms.

Q:How does spectral response depend on temperature?

In wavelengths shorter than the peak sensitivity, spectral response has almost no temperature dependence. In longer wavelengths, it has a positive temperature coefficient.
