What is the price of an 850nm laser diode

850nm laser diodes range from around $20 for low-power modules to several hundred dollars for high-power or fiber-coupled units. Typical Price RangesLow-power compact modules (1 mW): These are small, self-contained laser diode modules suitable for alignment, measurement, or bar code scanning applications. Prices start at approximately $20–$50 per unit, depending on the supplier and included accessories (e.g., Edmund Optics).

Medium-power diodes (40–250 mW, fiber-coupled, DFB): These single-mode or fiber-coupled diodes, often used in laboratory or industrial applications, typically cost $200–$500 per unit. Optional features like fiber Bragg gratings (FBG) or integrated drivers can increase the price. High-power pulsed or peak-output diodes (up to 550 mW): High-performance diodes designed for pulsed operation or specialized applications can cost $500–$800 or more, depending on specifications, packaging, and testing.

Factors Affecting Price

Power Output: Higher output diodes are more expensive due to increased manufacturing complexity and thermal management requirements. Module Type: Fiber-coupled, DFB, or turn-key bench-top modules with integrated drivers cost more than bare diodes. Manufacturer and Supplier: Brands like AMS Osram, TT Electronics, and Wurth Elektronik may have different pricing tiers, and distributors like Mouser or Farnell offer varying inventory and shipping options.

Optional Features: Accessories such as focusing lenses, line generators, or integrated GUI control modules can add to the cost.

Summary

For general budgeting: Entry-level 850nm diodes: ~$20–$50Laboratory-grade single-mode/fiber-coupled diodes: ~$200–$500High-power pulsed or specialized modules: $500+ Prices fluctuate based on specifications, supplier, and optional features, so checking distributor websites like Mouser, Farnell, Edmund Optics, or Laser Diode Source is recommended for the most accurate and current pricing.
