Price of 940nm Laser Diode in the United States

The price of 940nm laser diodes in the U.S. ranges from around $10 for low-power modules to several thousand dollars for high-power industrial units.Consumer and Low-Power ModulesLow-power 940nm laser diodes, typically Class 1, under 1.1 mW, are available for $10–$30 per unit on platforms like Amazon and eBay. These modules are compact, eye-safe, and suitable for biometric sensors, gesture tracking, and covert surveillance applications (Amazon) . Multi-packs or small breakout boards for hobbyist or sensor applications may cost slightly more, around $20–$50 depending on quantity and shipping .Laboratory and Medium-Power DiodesFor laboratory or OEM applications, pigtailed 940nm laser diodes with output powers up to 100 mW are available from suppliers like Edmund Optics. Prices for these modules typically range from $150 to $500, depending on the integrated driver, fiber coupling, and power output . These are designed for plug-and-play operation and are suitable for precise laboratory experiments or industrial sensing.High-Power Industrial DiodesHigh-power 940nm laser diodes, including fiber-coupled modules from 200 mW up to 200 W, are offered by companies like AeroDIODE. Prices for these units vary widely based on power, configuration, and driver integration, generally starting at several hundred dollars for low-wattage units and reaching thousands of dollars for multi-watt or turn-key systems . These are intended for industrial, medical, or research applications requiring high stability and precision.SummaryLow-power consumer modules (≤1.1 mW): $10–$30Medium-power lab/OEM diodes (up to 100 mW): $150–$500High-power industrial/fiber-coupled diodes (200 mW–200 W): $500–$several thousand Prices vary depending on power output, packaging, and supplier, and shipping from U.S. vendors may affect the final cost.
