How Long Does The Laser Diode (LD) Last?


The LD lasts for approximately 50,000 hours at 40°C with a failure rate of 10%. It lasts for approximately 100,000 hours at normal temperature (Approx. 25°C).

The life of a semiconductor laser is approx. 50,000 hours. (Failure rate: 10%, ambient temperature: 40°C)

*The life of a Semiconductor laser becomes approx. 50% by increasing by 10°C.

Smart Sensors have an included function for laser life degradation detection.
