A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The spectral range is typically 400–1100 nm, covering visible to near-infrared wavelengths. The peak sensitivity is usually in the 850–950 nm range for silicon photodiodes. Confirm the exact range for your model.
Smaller pixel pitch improves spatial resolution but may reduce sensitivity. The typical pitch is 25–100 µm. Choose a pitch that balances resolution and signal strength for your application.
Output can be analog or digital. Analog outputs provide raw signals for external processing, while digital outputs simplify interface with digital systems. Verify the output type and signal levels with the manufacturer.
Common issues include reduced signal amplitude due to contamination, increased dark current from temperature stress, and damage from electrostatic discharge or excessive light. Operating within specified temperature and voltage limits is critical.
