What is the price of a 940nm laser diode

The price of 940nm laser diodes varies widely, ranging from around €10–€50 for low-power modules to several hundred or even thousands of dollars for high-power or fiber-coupled units.Low-Power Laser DiodesFor laboratory or OEM applications with output powers up to 100 mW, pigtailed 940nm laser diodes are available for approximately $50–$100 per unit. These modules often include an integrated fiber and driver for plug-and-play operation, requiring only a 5V power supply, making them suitable for research or small-scale applications (Edmund Optics) .Mid-Power and Fiber-Coupled ModulesFiber-coupled 940nm laser diodes with single-mode or polarization-maintaining fibers, and output powers in the range of 200 mW to a few watts, are typically priced from $200 to $1,000, depending on features like narrow emission spectrum (FBG) or integrated drivers (AeroDIODE) . These are often used in industrial, medical, or sensing applications.High-Power Laser DiodesHigh-power 940nm laser diodes, including turn-key modules with 10–200 W output, can cost several thousand dollars, reflecting their specialized design, integrated control software, and high stability for industrial or research use (AeroDIODE) .VCSEL and SMD OptionsFor VCSEL (Vertical Cavity Surface Emitting Laser) 940nm diodes, such as those used in facial recognition or 3D sensing, prices start around €10–€50 per unit for small quantities, with bulk pricing available from distributors like RS Components or Farnell Germany . These are compact, surface-mount devices suitable for electronics integration.Wholesale and Online MarketplacesOn platforms like Made-in-China, 940nm laser diodes for applications like smart home or iris recognition can be purchased at wholesale prices, often lower than retail, depending on order quantity and supplier .SummaryLow-power (1–100 mW): ~$50–$100Mid-power fiber-coupled (200 mW–few W): $200–$1,000High-power modules (10–200 W): Several thousand dollarsVCSEL/SMD 940nm: €10–€50 per unit, depending on quantity and supplierPrices vary based on power output, fiber coupling, module integration, and manufacturer, so it is recommended to check distributor websites or request quotes for precise pricing.
