What is the price of a 635nm laser diode

635nm laser diodes typically range from $10 to $300 depending on power, packaging, and module integration.Typical Pricing by TypeLow-power TO-can diodes (1–10mW): Standard 635nm diodes in TO-18 or TO-56 packages, such as the 5mW D6355I or 10mW QL63F5SA, are priced around $10–$25 per unit at distributors like DigiKey .Pigtailed or fiber-coupled modules (1–10mW): Modules with integrated single-mode fiber and FC/PC connectors, such as those from Edmund Optics, are generally priced around $100–$150, depending on the included driver and fiber length .Turn-key or high-power single-mode modules (10–80mW): Integrated modules with built-in drivers, pulse shaping, or CW operation, like those offered by AeroDIODE, can range from $200 up to $300 or more, depending on power output, fiber type, and optional features .Factors Affecting PriceOutput Power: Higher power diodes (tens of mW) cost significantly more than low-power laboratory diodes.Packaging: TO-can diodes are cheaper, while pigtailed or butterfly packages with fiber coupling increase cost.Integrated Drivers: Modules with built-in drivers or turn-key solutions are more expensive due to convenience and performance optimization.Pulse vs CW Operation: Pulsed diodes with precise timing control or nanosecond pulse shaping are priced higher than standard CW diodes.SummaryFor budgeting purposes, a basic 635nm diode can be expected around $10–$25, while fiber-coupled or turn-key modules typically range from $100–$300. Prices vary by distributor, power rating, and additional features, so checking current stock and datasheets from suppliers like Mouser, DigiKey, Edmund Optics, and AeroDIODE is recommended .
