Reference Price for North Asia 635nm Laser Diode

The reference price for 635nm laser diodes in North Asia typically ranges from around $5 to $50 per unit, depending on power output, module type, and supplier. Price OverviewLow-power diodes (1–5 mW): Compact micro LDM modules, suitable for alignment, positioning, or barcode scanning, are generally priced around $5–$15 per unit (Edmund Optics). Mid-power diodes (10–50 mW): Standard 635nm diodes for general-purpose applications, including optical communication and measurement, are typically in the $15–$30 range per unit (Alibaba, Mouser).

High-power diodes (50–200 mW or more): Industrial-grade modules with thermoelectric cooling, high spectral purity, and polarization control can cost $30–$50 or higher, depending on features and supplier.

Factors Affecting Price

Output Power: Higher optical output increases cost due to more advanced semiconductor design and thermal management. Module Type: Integrated modules with optics, automatic power control, or TECs are more expensive than bare diodes. Supplier and Region: Prices vary between distributors like Mouser, DigiKey, and Alibaba, and may include shipping or import fees for North Asia.

Certifications and Reliability: IEC60825 compliance, ruggedized packaging, and long lifespan (10,000–50,000 hours) can increase unit cost.

Purchasing Tips

Compare multiple distributors to account for regional shipping and taxes. Check datasheets for operating voltage, current, and thermal requirements to ensure compatibility with your system. Consider bulk purchasing for cost reduction if large quantities are needed.

Ensure proper handling and storage to maintain diode lifespan and performance. In summary, for North Asia, a typical 635nm laser diode can be expected to cost between $5 and $50, with the exact price depending on power, module features, and supplier choice.
